from Pellissippi Parkway and points west:
Take the Parkway to Dutchtown Road, exit east (towards Knoxville) onto Dutchtown. Go straight through a 4-way stop, around a bend, and turn left onto Bob Kirby Road (just before the Webb School). Take the first right onto Cortez Drive. Proceed to the bottom of the hill, Diane & Kevin are on the right at #9708 Cortez Drive.

from I40/Cedar Bluff Blvd and points east:
Exit I-40 at Cedar Bluff. Take the right fork at the ramp, turn left at the light at the bottom of the ramp, then turn right at the light onto Cedar Bluff Blvd. Go through one light. Turn left at the second light onto Dutchtown Road. Go roughly a mile and a half and turn right onto Embarcadero Drive (if you get to the Webb School, you have gone a little too far). Go one block and turn left onto Cortez Drive. Kevin & Diane are in the third house on the left, #9708 Cortez Drive.
