I also like the southwest. I've been to Phoenix a couple of times, and yeah, it gets hot... but like they say, "it's a dry heat!" And that's really true. I can deal with 110 degrees and 20% humidity, no problem. It's those 90 degree/90% humidity summer days here that are killers. I swear, you can sit perfectly still under a shade tree and still break a sweat!
Harry, I was concerned about moving to the South (NC) back in 2005 because of the humidity but the big difference here versus Chicago is that once the heat and humidity set in,it sticks around and you get used to it, unlike the yo-yo effect of Chicago's wacky summer weather. I had a heck of a time going from 90 degrees and a dewpoint of 72 one day and the next it would be 70 degrees and a dew point of 48 in Chicago on any given day in the summertime. I think this past summer you had more 90 degree days in Chicago than we had here in NC, and when I visited at the end of July, it was nearly between 98 and 101 degrees 6 out of the 7 days I was there!
You would enjoy that Mustang a lot more if you lived elsewhere, something to think about.
