What can Alaska Alpine Adventures do to strengthen their business?  How about, for starters, not letting two almost 70-year-old women handle a rubber canoe by themselves, and put an age limit on adventure tours.  A lot of other Alaska tourism business DO factor in age when it comes to the level of danger for selling a tour package.  It was important for the owner to point out that one of  the women was "tough as nails."  But not tough enough to keep her rubber canoe upright or fend off a 10 mph moving river.  Heartfelt condolences to these women's families and friends.
