Here's a spot I forgot to mention if you are North bound in the Smokies.
When you are approaching the Tunnel, you will come to an unmarked fork in the trail (this is past Gold Mine Loop and the Tunnel Bypass trails). Take the left fork up. If you look up this fork you will see some wooden barriers or what might look like a parking lot or something not too far away (or that's what it looked like to me). Actually this is the end of the old Lake Shore Drive and leads quickly to the Tunnel.
The right fork goes down and is tempting, because you are traveling downward to Lake Shore Dr and Noland Creek Trail. But take the left fork even though it looks like it might go back up.
Hutch, Rabbit and I will all be at Trail Daze. Look us up.
