Looking for a little advice on The McKenzie. Our usual Eastern Oregon camping/fly fishing trip has been canceled

. We are trying to plan a trip to the McKenzie. Never been that way, but man, all the books make it sound real nice. I have a drift boat that we can bring or leave at home, the kids want to swim, fly fish and enjoy some camping. We need half way decent facilities to tent camp. Any recommendations on a campground would be greatly appreciated!!
