Maybe you'll find someone who has a corner table who is willing to share a section of it with you... It does happen.

After having a shared table in '94 and having to give up my purchased table in '95 due to family illness, I decided to vest pocket it in '96 and, upon walking into the room I went over to Albert Rollins' table who I knew real well since he visited F.U.N. every year and greeted him. He had a corner table with one table being empty which he planned using for those who might want to trade or simply use the space to gather about and, when he found out I did not have a table he offered me the corner section where both tables joined. At the end of the show I gave Al the cost of his table and a little bit more while every square inch of his space was being utilized, constantly by several chippers for the duration of the show..

Good luck, Fred.
