Guys & Gals,
Just a suggestion that's worked well for some of us. Before you leave on your trip, drive, walk to the venue, whatever travel mode you use - post your seat numbers. That way anyone who REALLY wants to see you can look you up.
My wife thought I was nutz the first time I did it (you know internet stalkers and the like, LOL) but it's always worked out quite well. It also helps separate the wheat from the chaff... If someone has your seat numbers and can't find you well I'd say they really didn't think it was worth the effort. And we've met some very nice folks that way.
