In Elko, Nevada, take Idaho Street (the main street that runs alongside I-80) to 12th street.  Go east on 12th to Lamoille Highway and go North.   Go about 2 miles up the hill to the stop light.   Turn right at the light.   This will take you to the entrance to the hospital parking lot.   Instead of turning right into the parking lot, turn left across the cattle guard onto the dirt road.   This will take you back to the track.
