Traveling East on 199, past Monticello, you will turn left at the John Tyler Hwy/RT 5 exit.
After you turn, bear right on John Tyler Lane like you are headed into town toward Walsingham Academy.
Turn right on Professional Drive and immediately turn into the parking lot at the rear of the first building on your left.
You should see signs in the front yard of the building.
Parking is in the back of the building and come in the back door. WGL is on the second floor.
