It took awhile, but I came to realize my parent's love affair with retirement in WY. They detest humidity, and while they may hit 90 here and there during the summer, its sunny all the time, and dry. It's got all of the recreation they were seeking, and not the extreme/nastiness of the NE and WI winters they experienced much of their life. Of course WY is a huge state, and they are knowingly isolated, but they could've picked all sorts of non-high desert areas and gotten socked by snow, wind and cold. Different strokes for us all.
Fla. is a seasonal stop for me, same with the PHX valley. Wouldn't be caught in those places if I can help it between April-September.
