I have been fortunate enough to live in both types of mountains. I grew up in the Blue Ridge mountains of Virginia, but also lived in Wyoming for a while with a 360 degree view of the Teton Mountains from my cabin. I have hiked and horseback rode in both. The air is thinner in the Tetons, but the air is cleaner (not much in the way of pollution since the factories are much fewer out west). However, if i had to choose, and now that I am more into cycling, I would choose the Blue Ridge. The Tetons had no foothills and required more caution (wildlife, mountain climbing, etc.), whereas the eastern mountains have more accessibility should something go wrong (i.e, emergency help, etc.) Both types are absolutely gorgeous however and I consider both states my “home”. Alas, I now live in Florida and crave a good hill climb every now and then. I plan to retire further north in the Blue Ridge, and I definately want a nice mountain view from my new home and studio! Nice survey - it will be interesting to see what other responses you receive.
