I was there, and tried to find Zion...but managed to miss him every time I stopped by the booth. Nuts! Sorry we didn't meet, Zion.
I did, however, run into none multiple times and wound up hanging out with him quite a bit on the last day...along with some old-school AOL SW group guys, some of whom I've known online for centuries. Some great times there! The discussions we had on the last night were a blast, punctuated occasionally by the passing-by of a major or minor celebrity. At one point we flagged down Ben Burtt for a short chat when he passed by our table at the hotel.
Come C6 (you know it's gonna happen), we really should organize some sort of ot.com get-together. Discussing the unaltered trilogy, film preservation and other such topics is fun online, but it's even more fun in person with fellow-minded fans.
