I did browns and the gorge with redbeard
At 1000, browns looked great for a kayak and was good fun for a raft w/o gear, except river libations. it was a litle boney. At 750, a raft full of gear would have to pick its way down, carefully.
we decided against fractions at 1000. but we were also looking for action, which we found in the gorge.
camping at the pay sites is well worth it, cheap and good river access w/o wrecking the place. watch out for those rangers
