i have run shoshone hundreds of times. i have backed down the ramp to unload my boat at least a half dozen times. with that being said, i know it is illegal. when no one is there, especially the forest service jerk wads it is not a big deal. i run it solo on a 14' cataraft when hardly anyone else will, i have run it a 12,000 and down and consider 4500 to 6500 the most challenging level. above that it is mostly washed out. i cant recall ever hitting a rock in my boat which is considerably wider than a dory. if a guy wants to run it in a dory go for it, an experienced oarsman should have no trouble avoiding rocks and picking a line that works for him. i havent rowed a dory in a long time but if i remember right they are alot more nimble than a 16' raft. the only concern i would have in a dory is taking on water from splash over.
the guy who chimed in that the author of the thread is an idiot, is himself an idiot, and should keep posts like that to himself. it does no one any good to insult someone for asking a legitimate question. people have told me that i cant take my boat down the crystal, but i did and it was great, people tell me all the time not to solo big water, but i do it all the time. if i waited around for someone else to go with i would spend alot of time at home. shoshone is alot of fun at high water, it only happens once a year if we are lucky, if you are afraid of it at 6000 plus then stay off it, but dont tell others that they should stay off it. it is closed to commercial for legal reasons more than the difficulty of running it.
