7:29 p.m. -- Comments from provisional Pro Stock Motorcycle pole-sitter Angelle Sampey following the second round of qualifying:  

"This is actually my favorite race of the whole year because I love Las Vegas and I love Halloween - it's my favorite holiday, next to Christmas. We had a great run. We've had, I think, all of our bad luck in the beginning and the middle of the year and I'm really hoping these last couple of races has mercy on us and we get to do well for our sponsors who have been so wonderful. I've won a race -- at least one -- every season and it's really, really killing me that we haven't (won this year) because I know that I can and I know that my team can. We haven't shown what we're capable of."

7:15 p.m. - Comments from provision Pro Stock pole-sitter Jeg Coughlin following the second round of qualifying:  

"The conditions today are fantastic - Mother Nature really blessed us today. We got a little bit of heat out there but the cloud cover kept the track very, very tight. A lot of teams really

---------------------------------------------------------------------------------------------------------------------------------------------

7:11 p.m. - Comments from provisional Funny Car pole-sitter John Force following the second round of qualifying:  

"The track, I thought, was excellent. It's good to be back and it's good (to be on the provisional pole); it's been a while. I'm not the person that I used to be (before the accident last year) because the doctors say I can't take another hit like that - I'm too old. I think that holds (crew chief Austin) Coil back when he really wants to go to crunch time. I said to him, ‘let's go for it or let's go home.' "

7 p.m. -- Comments from provisional Top Fuel pole-sitter Tony Schumacher following the second round of qualifying:  

"We went out there and it shook at 60 feet. That's always uncomfortable because we have not had the most success on Friday nights, we just haven't. It shook and then it just went into warp speed. The circumstances where you've got to qualify to be the champ and you've won 14 races, you don't want it to be anticlimactic where you just squeeze in; you want to prove the point, I guess."

---------------------------------------------------------------------------------------------------------------------------------------------

6:51 p.m. - John Force took advantage of cooler track temperatures and powered his Ford Mustang Funny Car to the provisional pole under the lights at The Strip.

Force's pass of 4.062 at 307.37 mph gave him the top qualifying position after two rounds. Cruz Pedregon was second and Melanie Troxel was third. Ashley Force was fourth fastest and Funny Car points leader Tim Wilkerson was fifth.  

In Top Fuel, Tony Schumacher regained the provisional pole with a run of 3.781 at 316.60 on the final pass of the evening. Antron Brown, who had grabbed the provisional pole earlier in the session with a run of 3.812 at 315.49 mph, was second and Larry Dixon was third.

---------------------------------------------------------------------------------------------------------------------------------------------

5:50 p.m. - Midway through the second round of pro qualifying, Angelle Sampey (Pro Stock Bike) and Jeg Coughlin (Pro Stock) are the top qualifiers and both have established track records.  

Because an earlier oil-down stretched out the second round of qualifying until early evening, Coughlin had ideal conditions when he made his second run and improved to a track-record 6.703 at 205.47 mph.  

Sampey's first-round run of 6.993 at 188.34 mph kept her on top of the speeds charts.

4:55 p.m. - The two annual NHRA National events at The Strip always are the most important races of the season for Las Vegas resident Rod Fuller. But this weekend's ACDelco Las Vegas NHRA Nationals has taken on even more importance for Fuller now that Tony Schumacher has all but clinched the Top Fuel season championship.  

"I kind of feel like we're a wounded animal backed in a corner right now and we've got nothing to lose," said Fuller, who was sixth after the first round of Top Fuel qualifying.

"I'm at my home track, the championship is pretty much sealed up for Tony and we're just going to go out there and have some fun and be loose and go for it."   Fuller said he is taking a more active role in the tuneup of his David Powers-owned Caterpillar dragster this weekend.  

"I'm going to have some decision on the tuneup this week with my crew chief, Fuller said. "That thing is either going to run low e.t. or nor e.t., I'll tell you that."

3:55 p.m. - After a lengthy oil-down delay, the final pair of Top Fuelers finally got on the track and points leader Tony Schumacher laid down the fastest run and grabbed the provisional pole as the first round of pro qualifying concluded.

Schumacher's run of 3.847 at 317.19 mph was the quickest and fastest of the session. Clay Millican was next at 3.889 at 315.42 mph and Larry Dixon was third at 3.905 at 311.20. Schumacher can clinch his fifth consecutive World Championship on Saturday by qualifying for Sunday's final eliminations.

2:40 p.m. - The Pro Stock cars driven by Greg Anderson and Jason Line have been considered the "hometown cars" at The Strip because Las Vegas businessman Ken Black owns them.

Another Pro Stock entry figures to have some local rooting interest this weekend - but not because of the owner or driver. The ACDelco Cobalt, driven by Kurt Johnson, also has a strong tie to Las Vegas because one of the team's three full-time crew members lives in the Valley.  

Brian Strait of Las Vegas is in his first season as a member of Johnson's team after Strait came to Johnson's aid earlier this season after the unexpected departure of a junior crew member. While his role with the team was supposed to last only a few races while he trained a replacement, Strait became a more permanent fixture when the new hire didn't work out.  

Strait, who has known Johnson since the two were in high school in Minnesota, is in charge of the back half of Johnson's Cobalt and handles everything from the tires and rear suspension to repacking the parachutes after each run.   Strait truly is a "weekend warrior," who flies in to each race. While he's in Las Vegas, Strait serves as the general manager of the Las Vegas Ski and Snowboard Resort at Lee Canyon.

1:25 p.m. - The first round of qualifying in Pro Stock is complete and Jeg Coughlin finds himself atop the speed chart with a 6.706-second run at 205.29 mph. Allen Johnson is the second-fastest qualifier and Greg Anderson, a six-time winner at The Strip, sits third.

---------------------------------------------------------------------------------------------------------------------------------------------

12:50 p.m. - Angelle Sampey got Pro Stock Motorcycle qualifying off to a quick start by turning in the first sub-7-second pass in the category at The Strip at Las Vegas Motor Speedway.   Sampey, a three-time World Champion, made a 6.993-second pass at 188.23 mph on her first qualifying run today and is the top qualifier after one round.

12:29 p.m. - At the conclusion of racing this afternoon, fans are invited to stick around for a free post-race party on the general admission side of the track (the side closest to the right lane) featuring two sets by Danny Dean & The Rockin' Rebels.
