note Those are great stories, Ken.   Alan Singley was quite the
pioneer, along with Robin.  Where Holcomb Cr. "leaps off the mountain" there's a Class 5-6 drop that squeezes through potholes choked with wood.  I hiked up by it one time when Overflow flash-flooded while we were on it - went to 4.5ft  Singley's Falls was huge (which we ran), but Twilight had big terminal holes - a tough portage.  Managed to paddle down to 3-Forks and bailed; like others did that day as well.  Got to the takeout at 11PM where Woody was waiting with sandwiches - I was amazed.

Pretty impressive that you guys were running this stuff in the 70's.
