That is what I was gonna say.
A Company that I think was called "Blackwater Adventures" also used to run this commercially (may have been absorbed in Precision??) When in college I would be swimming in the Big Sandy near the confluence w/ the Cheat and see these commercial trips float by and I couldn't believe they had such large boats in what looked like a creek at this point. I thought what could possibly be so fun on this river in that boat...THEN I got into rafting and found out!
BA would also run Moats Falls on the Tygart in WV. Basically a 14 foot clean vertical drop....there's some youtube vids of it somewhere, pretty crazy stuff-both of them.
Some day I wanna catch the Big Sandy Running-someday! Wanna go R2 this sucker?
