Quoted from Alan_L:

First timers: don't hesitate to introduce yourselves to a stranger. It's not as though you're at some snotty art show where they are going to say "Who the f*** are you?". We're all friends here.
If there is a big line at a game and you're in front, offer the guy(s) behind you to play a multiple-player game. It's more fun to compete. (Where did I get that from?)
Wear comfortable shoes, take some Ibuprophen, bring hand sanitizer, and, bring some cash. Because once you attend a show, you will probably catch The Disease. The hook will be in your mouth but you won't feel it as the hobby reels you in. You must have one. You must have more. How can I get one of these in my car? How does this thing work? I don't care, I'll figure it out. She'll understand.
God help us.

I will have pinside laminates. You need a lanyard. I will be in the flea market area.
