That is awfully late, be careful. Might even wait until morning... if from the Knoxville area. You likely won't see a soul, or have cell service through Deals Gap without a Sat phone (which I do not have). West Buffalo is formed by two creeks; Squally and H...... ? Right above the confluence of the two is a great run of about 50 or yards or so of bouldered pockets, enclosed by trees. Squally is full of wild rainbows, small, but lousy with them! I bet you all will be pretty far up West Buffalo, maybe actually on Squally.
