I'm from Kentucky, and we're well hydrated in the summer here too, but it tends to be dry in the wintertime (like right now). We get it all here. I've been in the deep South and I just spent a month in Connecticut. I don't know which is worse, the humidity in the summer in Alabama or the dry winter air up north.
The light is dimmer in the north, I always miss the southern light and feel a sense of relief on seeing it again.
