Susan, I wonder how much your perception of "humidity" might be affected by where you CURRENTLY live
I moved from California to TN and I found it to be VERY VERY humid. Of course, I didn't really grasp until I was East of the Miss that the Western states are incredibly dry compared to most of the country. I suspect that if you're moving from someplace like, say, Ohio, or Arkansas or even Nebraska, that the contrast wouldn't be as marked as coming from CA, NV, AZ, etc.
I found it funny that my friends in TN were so worried about me moving to that incredibly humid state--Washington!
They just had no idea.
BTW, I was in Knoxville when in TN and different parts of TN will be somewhat different too (like, you would have to PAY me to live in Memphis or any city on the Miss!).
BTW, if you have someone in the family with bad allergies or asthma, you should investigate closely if you consider TN. I ended up with some very serious problems when I lived there--I hadn't realized that the Tenn Valley is one of the worst areas in the US for general "hayfever" type allergies & molds. And honestly, I'm not trying to talk you out of moving there; if it wasn't for my allergies and family situation, I would GREATLY PREFER the people and pace of life in Knoxville over anywhere on the West Coast (CA, OR, WA).
