Alan, can you give us a list of your top 5 National parks, and tell us why you rated them? I have a limited experience with them--there are a few in the Northeast, but nothing like the big ones--Yellowstone, etc. I've been to the Delaware Water Gap in NJ, and I've vacationed close to the Appalacian Trail in a couple of states, but never walked it. I'd love to hear the ones you would recommend. (Anyone can chime in here, but Alan's the one with the RV and a ton of stamps in his passport)
