Just a little info on the advertising thing:
I checked into reasonable forms of local advertising and one that I thought would be great would be a billboard next to the freeway that's only 1 1/2 miles from out track - It cost between $1,500.00 (crap location) to $3,500.00 PER MONTH FOR A 6 MONTH DEAL!!! Tough to advertise in any mainstream form when the $$ amounts are way out of reach for most hobby shops.
