Even though there wasn't a lot of Trek subject matter here, I went in uniform. I made a new headpiece, which I think turned out pretty good. Here's a picture:

Big crowd there, in the hundreds if not thousands. Lots of comic book artists and science fiction themed vendor booths. One could spend lots o' money for a lot of neat stuff. Also lots of folks in costume, with everything from Japanese anime to Star Wars characters. I think the attendees got a kick out of seeing a Klingon, too. I must have posed for at least a hundred pictures. Here's one of them, me with the eleventh Doctor from Doctor Who:
All of the celebrities I met were super nice. I had a cool chat with James Marsters about New Orleans music and how unique the city is.
There was a costume contest that evening with many great and original costumes. When I was called to the front, one of the judges asked me if I knew any Klingon poetry. I told her I knew Klingon songs, so, she asked me to sing. I sang the Klingon Battle Song in Klingon, which was enjoyed by the judges and others attending. I didn't win anything, but it was a blast.
I have to give props to the folks that ran the convention. It was very well run and I heard no complaints. I'm sure they will be back next year and I'm sure I will be.
