Good one 73, great memories just from your post.
Growing up in Wisconsin the smell of popcorn at a high school football game with a chill in the air, finally beating the oppressive humidity and wearing a jacket. Not sweating in a tree stand with a bow like opening season, just a cool breaze and fall colors, taking it all in. Late fall you can hear everything in the woods, even more so than all the wonderful smells. Hooves in cracking leaves in a fall woodland draw perched on a deer stand must be experienced. I always liked the smell of burning leaves too. My brother in Iowa said it best, he wished October was 70 days long. Its the end of a oppressive hot muggy summer, and just perfect weather.
Nevada fall is pretty much the way things are supposed to be as far as weather though. Cool almost cold nights with the windows open, with comfy covers, and 80 degree humidless days. Too bad it lacks what the Midwest brings in October and November in relief and fall colors. But it does seem to last forever. And yeah, it's sweet.
This is the time of year I envy the Midwest, so I take several trips there. Too bad it is the prelude to 4 months of uglyness! Well to be fair, the first few snow falls are awesome, but then it turns out to be a pain in the arse. Then it melts and it's miserable for 2 more months. Sure is nice to visit though.
