I'm going with 5 friends tomorrow! SO excited. I have a lot of booths I want to visit. One of my friends and I are both going to be in the market for new horses this year, so we're going to have a lot of fun looking at horses, demos, and new goodies! Probably not going to watch clinics because we won't have a ton of time to spend there, but I may go back Sunday by myself and view some if I have time.
A warning to all re: restaurants in the area from a Harrisburg local (I live 3 miles from the Farm Show complex) - the Burger King across the street from the Farm Show Complex is one of the dirtiest and nastiest places I've ever been to, with some of the meanest and uncaring workers. AVOID IT at all costs! If you want a good dinner, get on I-81 going North and hop off at exit 69/Progress Avenue, literally the next exit up the road. There is a Cracker Barrel, a Macaroni Grill, and a Starbucks in the "Shoppes at Susquehanna" shopping center. You just have to cross through the light onto Valley Rd when you get to the light at the bottom of the exit, and it's right there. If you turn left, there is an Arby's and a Your Place (YP) restaurant a little ways up the road, though I can't speak for the quality of YP.
