Will said to me after we climbed out of the Reservoir basin, "I could really use some pavement right about now." From the start of the Blackfoot Reservoir access road to this point, we had ridden 15 miles of some of the toughest gravel road in our lives. Granted, we have ridden everything from singletrack, dual track, old farm roads, and rights of way, but none of that compares to the roughness the gravel on this road.
Sometimes you would find a smoother patch and ride that or in the shoulder but that was more than not sandy and worse to pedal on. At one point I was riding trail that paralleled the road for a bit but that didn't last long, either.
