Dan
From Spearfish Lake Tales Wiki
Dan Plemmons started as a swamper with Canyon Tours in 1997 , at the same time as Jerry. He continued as a boatman after graduating from college in 1999.
In 2001 he had a seizure on a tripRR57 and had to be flown out on a helicopter. Jerry said "He had a brain tumor in high school, he told me once. He had chemo for a while and the doctors said they thought they'd licked it. But this spring, he just didn't strike me as being as well as last spring. Of course, I couldn't get the dumbass to see a doctor."
