Directions to the Race Parking:

From the South: 
1.  I-87 North to Exit 15A for NY-17N toward NY-59/Sloatsburg/Suffern.
2.  Use the left two lanes off the exit to turn left onto Rte 17N.
3. Continue north on 17 through the town of Tuxedo. Make a left onto Hillside Ave and park at the George Grant Mason School. Parking here is free. If you can't find parking here, try elsewhere in Tuxedo. There is a pay lot on E. Village Rd., by the north end of the train station, but you need the Park Mobile app. I think it cost $3 for the day the last time I parked there. The buses will pick you up and drop you back to the George Grant Mason School.

From the North:
1.  I-87 South to Exit 16 for NY-17 towards US 6/Harriman.
2.  Bear right off the exit and make a left at the traffic light onto Rte 17 South.

3.  When you reach Hillside Ave., make a left into the lot and park.
