I'm paddling a raft. Luke Nelson is paddling a board. We're both fly fishers from Idaho. We like boulder hopping small tributaries with Tenkara rods, but neither of us have a rod on this trip. We're in Bears Ears National Monument to run dirt and float water. Water that is so sandy, I know a hook set is not in the cards. I'm told native tribes find catfish here. Protected humpback chubs swim the San Juan River too, but with flows at 6,000 cubic feet per second instead of the average 2,000 cfs, the swift current isn't holding patience for casters so we paddle.
