Take HWY 60 east to 441 North(Yeehaw Junction) Turn left on 441 and head the entrance will be on your left about 7 miles up. You will pass a 3lakes entrance on HWY 60 but its not the right one.
i thiink the entrance is more like 12 or 18 miles up the road.
Seemed like 7, remember we were going 90-95mph, lol.
