I would have really enjoyed this. I don't know all the characters, but it just looks like a sh*t ton of fun! I'm also glad that you guys were able to get signatures from the Power Rangers. They were kinda cool in the day lol - I was a kid so that kind of thing rocked.
When I was living in the UK, I went to the premiere opening of Jay and Silent Bob Strike Back and Silent Bob was there in the teeny tiny cinema of Luton (well a very good look alike anyway)...that was the closest that I got to attending a ComicCon.
Thanks for sharing, but now I also want to go.
