I know many with RA who have moved to places like Arizona and while it is hot, they generally seem to say they thought it was an overall good move. You have to know your own illness, though, like for me I hate the heat so humid or not, I'd be miserable. If you can give it a try first that's always a good way to feel it out, if not I'm sure we have some community members here who can give their thoughts! Keep on keepin' on, DPM
