I also attended Megacon this past Friday. I had a great time. I wasn't there Saturday to experience the internet problem Bob mentioned above. I strongly agree about setting up all the comic book dealers in one area. It was annoying having to try and find some of them.
Too bad next year's show will be the same weekend as another major show, I will see what dealers will be at Megacon and decide if I will return next year. Normally, I would definitely be going.
Overall though, I had a great time and picked up some very nice books.
