Ok guys I will be coming from San Antonio, Texas up hwy 83. I will be staying in North Platt Neb. I have been to Sturgis one time and we rode to see the presidents, devils tower, through a cave, saw buffalo and a bunch of switchbacks where there were small bridges that we went under and a water fall on the side of the road. Its approx. 374 miles from North Platt to Deadwood. I need to try and see the above sights on the way to Deadwood. I am also leaving from there the next morning to Billings Montana. I need to know the best scenic route for that part of my trip also. Thanks in advance. It will be around the end of August, first week of Sept.
