Opinions on swap meets

Sell it here, not a captive audience and it would be safe. Or you could set up a stand with some pics and cell phone number. they wanna see it, call you up and set it up. I wouldnt even let the guy next to me monitor it. I bought an RB Vertex Mag with wires and an indexed crank hub in a box for $40 from a guy, I think he was the help putting out the boxes!!! "How much for the box of stuff? ...uh...how about $40? ...SOLD!"
