Thunder valley Marion SD

Anybody go to this track a lot? I have a 69 Dart that I am planning to do a lot of drag racing with next year. Wondering what dates are the best to go (all mopar, street car shoot outs). Looking for the most people to be there so I can get ideas on how to better my car and time slips.

Also anybody camp out at the track for the weekend (tents). Looking to drive my car to the track. (live 140 miles away)

How much fuel to bring?
