We live in east Texas..... we usually vacation in Rockport, on the Texas coast...not much cooler, but usually a good breeze and and change of scenery and we love the Texas coast and have been to most every spot on it at one time or another. We have hot and humid most of the summer! I don't think y'all get to deal with a lot of humidity in Arizona. Is this a blessing? I have no idea! LOL,LOL
I guess you learn to adapt to your environment. We bought an old house (1902) in May of '07 and spent 3 years redoing it totally on the inside. We still don't have central air or heat, but do have some room a/c units. I use my a/c in my sewing room when it gets hot in here....can't work in the sewing room and sweat! NEVER! I also don't sleep and sweat! NEVER! (well, only if we have NO POWER)
