I enjoy Ft. Lauderdale/Miami in the summer. It's no more hot or humid than the rest of the East Coast. In addition, there are torrential thunderstorms which cool everything down. The storms are interesting: one minute it's sunny, the next few minutes there's a huge rainstorm, and then it's sunny again. Also, pretty good SP selection there as well, and it's all outcall. Not as cheap or as much variety as Montreal, but probably the most for any US city. A lot of Canadians in Florida as well; it's one of the most popular areas that Canadians choose to retire in. I've seen plenty of Canadian SPs in Florida.
