travisl found Clackamas River Side (Traditional Cache)
OK, I'm on my way to the cache, and I have the option of taking a well-trodden dirt trail along the edge of the woods, or walking along the riverbank on those round shingle-stones. The deciding factor?
I swing around the end of the fence, and survey the teeming mass of park patrons (ok, there was about 20 of them). All of the babes are either too young or too porcine -- I take the dirt trail.
Nice stroll, nice river, nice quick find.
