Whitman was rafting on a commercial trip when his raft overturned, dumping him, his wife, and five others into the rapids. The other members of the group swam for shore; the doctor was washed over Little Falls. Dr. Whitman, who suffered from Asthma, was not breathing when he was pulled from the water moments later and could not be revived. SOURCE: Foster’s Daily Democrat, Dover, NH ; Rusty Bowman, Twin Falls, ID.

Those who suffer from this condition must take it into account when running rivers.
