Hello! I've bee doing this a little bit. I was in costume for the Galaxy Blood Drive part of the time, but also did some spotting. After that, I was in costume at the library on April 14th, and I was a spotter for the Autism walk.
Currently, I'm using the Stormtrooper armor my brother, Ron, made. I'm hoping to eventually get biker scout armor and use that, though. I've had a lot of fun with the troops I've already been to, and I look forward to future troops as well.
