Deputy Dog,
Take 25E from Morristown to Tazewell. In Tazewell, you will come to the red light intersecting 25E and 33, turn right and stay on 25E to Harrogate about 10-12 miles. In Harrogate, turn left at the second red light, this will put you on highway 63. Follow 63 approximately 2 miles, when you see right and left turn lanes appear in the highway turn left (I don't remember the name of this road off 63). After the left turn this road ends with a 3 way stop, turn right. Cumberland Gap H.S. is about a 1/2 mile on the left. Have a safe trip.
GO PANTHERS!
