its not that as easy as it sounds..."use a big parking lot, like target or something". with a LARGE company like a target, walmart etc, there are ALOT of hoops needed to jump through and it is nearly impossible to use something like that or else the SCCA or the Sunriders would have already have had an autox in something like that.
the lot at the dog track at tampa bay downs requires a minimum of 5million dollar insurance coverage which along with being very difficult to get, is quite pricey. The dog track on Gandy just flat out told me NO...after I had gone there about 4 times talking to different people.
making one of these events happen isnt as easy as it sounds. i promise, if it was, you would have a date for dday3 already. and dday4, dday5, etc. it'll happen, just hang in there.
