I live in Washington state and people immediately think of rain here, but I live on the dry side of the state and we don't get much rain and have low humidity. I don't think those of us who live in dry climates can quite relate to the humidity and vise versa as well.
I was talking about this thread to my DD on the phone yesterday and she recalled when she went to Alabama at age 16 or 17. She said she washed a cotton sweater and laid it out to dry and it never did dry. Things like that just don't happen here.
