Jeff, what is this "humidity" of which you speak?
Fall used to be my favorite season, too. (Though growing up northeast of the Northeast, "fall" ended sometime before Halloween, and was followed by "stick season," which was grey, dark, and cheerless.) And fall is incredibly beautiful out here, too, with snow up high and blue skies and aspens turning gold.
But it's also beautiful in a sad kind of way, and for some reason, over time, the sadness has seemed to grow compared to the excitement of that crisp feeling in the air. Maybe it's because fall never seems to last long enough any more. (Or maybe it's because my current job gives me all kinds of freedom during the summer, and then when September begins, every moment of my time is spoken for at least once. Which explains the getting-up-before-sunrise thing.)
It also could be that I don't live in a place with humidity any more. I wouldn't be able to stand an East Coast summer these days... I've gotten accustomed to living without sweat.
