I like the season, but here's a few things I've noticed about late season (wetside).
Usually last to chase the elk, but everyone else is pretty much cleared out of the woods (shroomers/brush pickers/day-trip-target shooters/etc).
Weather is usually good and cool, but tends to be rainy which affects some muzzys.
My experience has been that it has been cold enough that frost freezes all the leaves on the ground making it sound like walking on broken glass. And it takes forever to melt out in the trees, so it is constantly dripping and sounding like some movement when the drips hit the frozen leaves.
Vegetation has died back such that you can see farther, but the elk can too.
