traindaddy - The dealer halls are chocked full of venders, mainly with new products. There are some dealers with classic merchandise (postwar, flyer, etc.), mixed in amongst the aisles. You will be perfectly capable of spending the gdp of most Gulf states in those 2 buildings alone. There will be at least 3 fully operational layouts, and Lionel, MTH, Atlas, and others have great new product displays.
The member halls are filled with rows and rows of used trains and collections for sale. Some merchandise is priced to move, and some merchandise is priced to be there for the Fall show...and beyond.
It's been said that if you walk through each hall once, including hiking between each building, you will have trecked 7 miles.
Is going just for the dealer halls worth it? I'd say yes. Often I've had to race through the Orange hall at the end of the day, wishing I had more time to take in everything.
I hope everyone here attending on Friday stops by the CTT booth at 1PM, and meet the members of the forums, as well as the staff, and get your mugs photographed with the gang.
