This took Us 4 hrs (lazy float, slow paddling only about 1/3 of the time). The first hour through Knock Knolls area while very shallow was lovely scenery despite a lot of people wading and houses, etc. The river widens and deepens just a little after that with little tree coverage. The last half all began to look the same. Both put-ins were very convenient (although that day 135th access had a tube outfitter there and they took over the entire parking lot).
