I'd be surprised if you couldn't find a buyer at the 'drome. Usually there is a bulletin board with a classifieds section, no?
I haven't been selling anything lately but I have been seeing some really low priced bikes that scammers put up in order to get contact information. Sadly, I was fooled on one and gave out my number, never hearing from the seller but I was offered a "fantastic once-in-a-lifetime offer" on a time share in Nassau via text.
