I agree, the dealers room gets pretty packed after the first hour. Plus with the 2 hour early bird it's already pretty well packed at 10am. I was there in '09 and there were two rooms of models and just over 500 entries. This year was just the one room. Not sure of the numbers though.
They also need to get rid of the "kids in camo". If another one walks behind me that close next year and kicks my heal again, I might have to deck him.
