I personally think its fun. Ive done a few events back in 04-05ish. I totally agree with the rolling down the hill analogy!
I think they (FD) lack the structure (volunteers, club scructure, knowlagable staff, consitent rules) to have any sort of longevity. Short term, I think they will get what they want out of it, long term I cant really guess.
I dont mind how it is now around here. We have an event every month or so at the local circle track. They are usually on friday nights and go pretty late into the night. I usually volunteer. I have fun flagging and re-setting up cones. What I find strange is no one else really volunteers for the events. A lot of drivers are driving AND doing whatever they can to help the event run smoothly.
