I'm a huge fan of the smell of burning leaves (of course, that was before I moved to Chicago....where that smell doesn't exist).
But you're right, the different sights and smells of the fall get to me as well.
I was walking the other day during lunch here downtown and had to stop and stand at a corner for more than a couple minutes simply because it smelled and reminded me of gameday in AA. I think it was at the corner of Monroe and Washington, but I may be wrong. Either way, the smell hit me across the face like a ton of bricks and I immediately in mind was transplanted to the parking lot at Pioneer HS. It was weird but really, really neat.
