We were in Gatlinburg the last weekend of October last year. The higher elevations were brown (Mt. Laconte and Clingmans done) but the lower mountains and valleys were hitting full peak.
Normally here in North Alabama we are usually peak about the first weekend of November. Things seem to be a week early here but that's probably due to the drought conditions.
The problem is that here, most Forrest are red maple, sweet gum, and different varieties of oak. We don't have the bright sugar maples like up north.
