riding alone is certainly a personal choice....like any other. but frankly it is not much different that scuba diving alone. aron ralston is a good example. poor prep and a cavalier attitude cost him his arm. he had been back country skiing alone and buried himself in an avy a few months before having to cut his arm off to escape a freak accident in moab. as guys have said, if you go solo you better be prepped, smart, and take all precautions......including giving a good itinerary to someone. the fact is you never really ride alone.........murphy is always free to ride.
I do believe that he has gone on to summit all the 14 teeners in colorado solo.
not 100% sure though. guy is a stud, that is for sure.
