I've been up there the last 2 years with the yellow mustang registry. It really is for mustang lovers and it's a blast, and I'm all signed up and ready to go this year. As far as the rain, last year it rained on Friday, the rest of the weekend it was great. If it does rain, they have a great auto museum in Hershey which is about 25 minutes away. It's really worth the trip if anything gets rained out. Actually, it's worth the trip even if the weather is great. If it's hot, just take plenty of fluid containers and also those neck wraps you put in the ice coolers then wrap around your neck. Really keeps your head cool. I don't go to any shows without them. Can't wait for June.
