They have lake Powell. If you have not been, it fricken amazing. I did a family trip there, we rented a house boat and it was one of our more memorable vacations.The lack of warm swimming water is what makes the West a turn off for me in summer. The humidity can suck in the Northeast, but it means 80 degree lake water. Very little of that exists anywhere out West. Now if I was more into mountain biking, trout fishing etc, I could absolutely see why people love the summers out there.
Doesn't surprise me that New Hampshire is second on a list like this. NH is not the best at anything, but it's very good for virtually everything. Many NH folks won't admit it, but a large part of why it is a great place to live is because of the neighbor to the south most locals hate.
