Yeah, a place without NT would be pretty hellish, now that you mention it!
I couldn't live in the South with all the humidity either - we're often in single digits here and almost always below 20% (except during the monsoon), so the heat isn't as oppressive. 100 degrees with 80+% humidity would be brutality on a grand scale!
I visited a friend in Elko, NV (way up in northeastern NV) one July and it seemed like a real nice place - temps in the low 90's, we hiked, spent a lot of time outdoors and I really liked the climate, lack of crowds/traffic, etc. Nice enough that I actually thought about moving there. Then we went back to visit the following January - snow on the ground and the temperature never got above 18 degrees (F) the entire time we were there. Eff that! Elko was immediately and permanently crossed off my list of potential places to live right then and there!
I've been to upstate New York once and it's an amazingly beautiful place - it was during the fall when all the trees were changing colors and it was just an incredible scene. I can see why people appreciate the beauty, but I just wouldn't be able to deal with the winters.
We all have our own ideas of Nirvana (and thank God for that or else there would be umpteen million people screwing up the beautiful southwest desert for me!)
