I have never done it but it sounds like a lot of fun!
24 Hours of LeMons:
The 24 Hours of LeMons is an endurance racing series for cars costing no more than $500. Races can last up to 24 hours in length and will certainly test the durability of a $500 car. With the series name being a parody of the famous European endurance classic, the 24 Hours of LeMans, these guys are all about fun. The penalties and punishments for breaking the rules are as entertaining and often times even more entertaining than the racing action itself. With the fun, laid back atmosphere that the LeMons organization brings to the track, this is certainly one of the featured events at the Barber Motorsports Park.
