All spots may be sold but they sure as hell aren't filled. Seems to me if you buy a spot it should be a "use it or lose it" deal for the following year. What the organizers need to understand is empty spots don't attract spectators.
I lost 5 consecutive spots in 2010 because I subleased them out to the company I was working for, but they decided not to do it last minute so they didn't pay for them! If the spots are paid for the owner will have them the next year no matter if there is anything on those spots are not. Like I said earlier, quite a few vendors park their vehicles on single spots and the vehicle may not have been there when you saw it empty.
