Here is my input Lou:
1st, get rid of the 1st to enter gets 1st start position. too much politics there. Do a draw a couple days before the race, or the morning at the race, for starting position. Late comers start at the rear. For me to come back and race, this is the first step. We have been told before that we were 2nd to enter thus 2nd to start, and somehow there was forgotten entries that were before us.
I like your relaxed atmosphere and such, and inexpensive racing.
As far as classes, i think you should keep it simple. an 850 and down, and 851-1000 class. thats what bitd is considering.
