I've never wanted to move out of the south...........until now!!

Oh my goodness!!! It is HOT!! This is the third day of 100+ degree temperatures. I can't take it anymore!!! I've never wanted to move out of my beloved south, but this is crazy hot. I don't remember it ever being this hot for this many days in a row. It isn't over yet either! I'm ready to move to a cooler area of the country. Maybe it's time to look for a realtor who can find me a nice house where I only need my A/C for a few weeks a year. Does it stay reasonably cool anywhere in the states for most of the year? Montana? Washington (state)? New England? Anywhere?
