I attended as a vendor once, will never go back. Another good place to find magazines but the animosity between vendors when I was there is something I had never seen before.
it's been some 5+ years since i went but i wasn't super impressed with it then. definitely a letdown vs the chantilly show as it's a lot smaller and prices higher. but i missed the chantilly show and will most likely hit this tomorrow. there is also a show in dale city that looks to be roughly the same size - 170 or so tables advertised.
