You name it, you'll find it. I love the show and look forward to it every spring, although the crowds do get to be a bit of a pain.
There will be outfitters, vendors, and exhibitors for more outdoor related products than you ever knew existed. Plus seminars, displays of HUGE deer mounts... Hard to cram it all in one weekend.
WTA will have a booth set up, and if you're coming over be sure to stop by and say hello!
