Rob, conventions rule. Great for deals, people-watching, and reveling in being a geek (and their ain't NUTHIN' wrong with that!) Actually, these days there are more pretty girls attending cons than when I was a kid, due to the crossovers of anime/Japanese pop culture and the Goth scene. At SDCC 2000, I was awed by all the babes in Sailor Moon costumes and black leather corsets and dominatrix-gear! They're really not as bad as you think.
Of course, I got drunk and sang the entire old Spider-Man cartoon theme song into a mic, lounge singer style, on Marvel's stage, so maybe that helped.
