Boulder creek through town
I like to put in Just above the manmade drops, (below) calss IV section at bottom of canyon, and run to some little eddy, i think its at Boulder broker inn. But supposedly, theres a great place to take out further downstream on BC by the Raft/tube shop around 3600 arapahoe.
The run is definitely got some good solid III+ stuff. Very interesting.
I bike scout it, if they're dumping water out of Barker and it looks really high. (Which they often do over memorial day weekend.
Call me if you want to meet up. Number on first post.
