This huge lower limb on a Cottonwood tree looks like it might have originally been grafted onto the tree. Doubt anyone would bother doing that with a Cottonwood, but it did catch my eye.
Five years ago today I landed with my Virginia trees-colored Jeep Wrangler at Petites Gap on the Appalachian Trail for my traditional birthday hike. I miss that Jeep and that trail a whole lot!
