Bull Run

Not sure about optimal flows but I ran this stretch at 2300 or so today and I would say it's not a good run if you're limit is class III. If you're class IV or above then this level is great fun. Most rapids were clean down the middle, a couple nasty holes to avoid, and a little rebar thrown in to keep you on your toes. It'd be a handful in a playboat, but the surf would be GREAT! Looked as though it could be run much much lower as the river might channelize nicely. Too much higher and the waves would be pretty damn big, definitely approaching a big water feel.
