With only six test sessions allowed by NASCAR this season, veteran driver Mark Martin says the test at Las Vegas Motor Speedway may be the most important one this season. Martin, who has had five top-10 finishes at LVMS, including his win in the inaugural NEXTEL Cup Race here in 1998 and two Busch Series wins, says that preparing for the UAW-DaimlerChrysler 400 will benefit the team all year. "The practice in Las Vegas is important to us for a number of reasons," said Martin. "It's big because we are limited in our test sessions, so what we learn in Vegas will help us the rest of the season." Martin says that the three days of testing will help his team determine car setups for many other tracks later in the season. "We hope to learn enough to help us all year," said Martin. "We will be testing everything from springs, shocks, and a variety of different setups." "I hope this will not be my last practice at Las Vegas," said Martin. "I hope I get to test my truck there next year." Martin will join more than 40 other drivers at the Las Vegas Motor Speedway January 30-Feb. 1 for NASCAR Preseason Thunder Las Vegas. The public is invited to watch the test sessions free of charge each day from 9 a.m. to 5 p.m. Tickets for the March 10-12 NASCAR Weekend are available by calling 1-800-644-4444 or logging on to www.lvms.com.
