I've done many presentations for shows and clubs, but I'm not about to insinuate myself into the sponsor's plans. I proposed a casual authors' discussion table to F.U.N. and Central States; neither were interested unless I was paying full rate for a table. That is, the proposed concept was not of interest to them.
Beyond presentation's info or talking with collectors, the Florida and similar coin bourse events are not places to collect data, and add to the store of knowledge. (It's a lot like going to a big car show looking for a specific antique radio.)
