I enjoyed the run below Diamond Creek, the canyon and rapids directly below were fun and the transition as the canyon opens up makes for a change is scenery and brings completion to the trip.
Because it's mellow down there is not to say planning isn't needed, there's not a lot of good camping spots, so it pays to be mindful of that. I didn't find the helicopters that big an annoyance it's just what it is on that rio.
Have never done the night float thing, we were game for it but it never materialized. I did notice there were quite a few large tree snags, just breaking the surface or just under it and sometimes the river braided into places that were raft sticking shallow. Probably wouldn't be all that much fun to hang up several tons of rafted up boats at 3am.
Have a good trip! Were looking for a spot in 2016
