wow. old thread is old.
I plan to bring my Altair along. I also have Sentinel.. If there are enough ACR cosplayers going, I guess I will bring it along too. (Otakon was rather sad... I think I was the only ACR MP character during the photoshoot... until the late arrivals show up).
If you want a photographer to tag along, I am available too. I organized and photographed the NYCC AC gathering.
