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

I had been to Mopar Nats every year from maybe 1985 till last time, about 2003 or 4. Missouri to Ohio was 12 hours, hated that nasty place. One to Carlisle twice. Love it but way too far. selling parts helped pay for parts/materials for my builders. Or did it!???

Most fun I had was when I bought "all the parts" I wanted to pull from a 72 or 3 Ply Satelitte out of a friends bone yard. Darn cheap for all. This was maybe 1998 or 9. I hauled it all to Nats put up sign that said everything off a 73 Sat. and sold every darn piece. People were so excited to buy such as NO ONE takes parts of such especially back then! I made good E$ and made a lot of guys really happy. At that time, I had two nice ones back at home, a 73 or 4 base Charger 400 4 speed car one of 75 and a 73 318 Charger.

I had the haggle, I rather price my parts at a good price, fair to me and the buyuer.... but that is not the game 99% want to play.
