yeah the truck was darn clean for a day the the track. I don't know about marshalls with a vacuum (lol @ roomba) but I know 1 jerk with a muggy had to go around picking up rocks he kicked up all over it with a muggy
indoor track there- lake in the hills IL really really hard packed but alot of fun. Was a greenhouse in there sweat in your eyes driving humid. Should be fun for winter though
