Well, I took the plunge and got my plane tickets and convention tickets!
I'm still debating on what costume(s) to bring due to the checked baggage thing, but I'm leaning towards one Batman, and my Ghostbuster uniform (since Ecto-1 will be there!) Just have to make sure a charged proton accelerator won't cause any undue concern by airport security...
Yesterday, I put in a lot of work on the GB suit, wiring up sound effects, etc... Then we took several shots. Here's one that turned out really cool. Did some big damage to the trees in the back yard with that wild positronic ionized proton stream.
