In my youth (40), we did the Main in June 1995, the old ramp was 5.9 ft, @20K, and about 50K at Whitebird when we got off. My sweetie and 14 yr old son were in a WW canoe, I was in a solo canoe on a commercial raft trip. Chittum was the only rapid, everything else was washed out with boils and eddy fences galore.
At Chittum, my solo was on a raft with me, but hubbie and son ran, up right, Chittum. In hind sight it was probably one of the stupidist things i let them do. If something had gone wrong, well . . . Some place I have a picture of a big jet boat entering Chittum, next pic it's gone, then resurfaces, the holes etc were huge. One of the safety kayakers got sucked out and swam last half. A few days before one of my thigh straps blew out and it was several miles before a raft caught up with me.
Overall it was a good trip, and gave my sweetie the confidence to do the GC in a tandem canoe, but not with me or son. Balance of our Main, MF, & Lower have all been in August - very different
