On a more positive note, you can get some really good Mexican food in Yuma. Even the really lousy Mexican restaurants there are better than anything we have in Florida.
It does get serriously hot there in August. I think they hit 119 F last year. But, they have only about 2% humidity, so all your wooden furniture cracks, your skin dries out and flakes off, and it's impossible to wear contact lenses. A loaf of bread will dry out within 20 minutes after opening it. There are no such things as "sweat stains" on anybody's shirts. And you really have to like dust.
Back to the positive for a moment... Somebody told me once that the overall climate in Yuma is so conducive to good health that people have to leave the area just to die.
