You never know until you've tried. We have a bunch of posters who go expecting it to be awful and they find it. If you go looking for one specific thing and don't find it, you may get a sour attitude. But the other side is if you just go to learn, it can be fun. Really great, in fact. Spend a little time and watch the transactions. Watch the people. Even talk to some. What you find is people from every walk of life and probably every intelligence level. If you can't tolerate stupid people, it may be a problem. If you can laugh about it, you'll be fine.
We get a table and we do it so my table partner can talk to others. He loves it. We make all kinds of friends. Some stop at every show and talk with us. Others even come behind the table to sit and rest. We also watch the girls, good and bad. And the attire they choose to wear out in public. We have fun and like it.
