Most in TOS costumes, both series and movies. Though Trek was definitely a very very small minority compared to other themes. Obviously Anime themed characters were the most prevalent, though beautiful women in the authentic Princess Leia slave outfits were my personal favorite. Favorite panel was the Women of BSG. Very gracious and funny considering some of the incredibly stupid questions they had to field. They gave out T-shirts to people who asked intelligent ones. Best part of conventions like this is all the people dressed up as their favorite character and posing for pictures. There were literally entire families (mom, dad, kids, babies) dressed as superheros (But not a single "Incredibles" themed family as far as I could tell). Talked to one of the guys from Smith Micro (maker of Poser). Some good stuff coming down the pike for those who use it. Too much stuff to talk about in a single post. It's still going on as I post this, but came home early because of a hotel snafu and didn't have a second night reservation. Unless you want to pay 400+ USD for a single night in NYC, there were no rooms available withing easy driving distance. So I came home early. Drat. Sunday is the best day to get deals and discounts.
