What is the best/worst you've done when selling at a swap meet?

I drove all the way from Mo. to Carlisle twice, back in the 90s. The first time it was hot like now, no body was buying anything. All they did was walk around with a sweat rag and complain about the heat. It was HOT! This was maybe 93 or 4 or 5? Took me 3 days to sell a 70 perfect shaker hood for $600.
The second time, I took my perfect 71 340 Cuda survivor (but with a perfect repaint) that needed nothing. Triple back 4 speed car. Priced to sell in the swap area over by my buds parts. No one even nibbled. This was about 1996-7 and priced at $9000. Then a storm blew thru one nite, and put a bad scratch on trunk lid.
Carlisle is a great show but I have not had luck there! :BangHead:
