The sumacs and dogwoods are already giving us some color in the woods, and the crickets are singing. One of my favorite fall hikes is on the Courtois Creek Section along the bluffs at about the 4 mile point, just before the campground in the Huzzah Conservation area.

The photo above was taken at sunset and the scene only lasted about a minute, the maple trees were a blaze with color.
