One Lap of America will be running at MAM this coming Sunday, May 4th. I will be attending. It starts at 8am and goes till roughly 3pm. In the past, the fast cars went first, so come early! I believe it's free to spectate, but be prepared if they want $5 for the entrance fee. You can pm me for my cell number if you don't have it.
They're also running at the following tracks, but I'm only attending MAM:
One Lap of America - the Official Webpage
Nearly twenty-four hours a day driving with competition taking place as time trials on race tracks throughout the country. The event, as it always has been, is foremost one of endurance and vehicle preparation. No support crews are allowed. The tires that are used on the street are the same ones that are raced on (one set per team). Although scoring is based on performance at the race tracks, the vehicles and their drivers must survive over 5000 miles of driving interspersed with the finest meals available at gas station convenience stores. Personal hygeine takes a holiday and friendships (sometimes marriages) are stretched to the limits as these competitors battle fatigue, weather, traffic and the demands of high-speed competition.
Some noteables on the entry list:
Nissan GTR
Mongoose Motorsports GTP
Ultima GTR
Ford GT
Dodge Stealth RT/TT (no seriously!)
