A couple of Fridays ago, my daughter Charlie and I took a daring paddle on the terrifying and legendary Crum Creek — a harrowing 45-minute effort. We put in right above the Strath Haven Coulee Dam off Yale Avenue and fought the swift current back upstream. Multitudes of turtles guarded the banks, and shadowy fish darted fearlessly in the shallows. Past snags and sieves we maneuvered, watching each other’s six, conscious of many reports of the attack beaver waiting to ambush intruders.
