If the event does not fill up I welcome on site registration, however with that being said. it's best to pre-reg I am capping at 40 to make sure everyone gets enough seat time. (pre registration gets secured spot) I will only accept a minimum of 8 runs and fun runs. with much more then 40 cars the workers start to get punchy. these events are about fun and more seat time is the best way to offer that. The weather should be awesome, not too hot, and we are the only show in town that day. So I expect a HUGE turnout.
