Last night I took a short bike ride on the Great Allegheny Passage bike trail. I packed a small camera sling, grabbed the single speed bike I built from parts and off I went.  Just a mile into the ride I heard the sound of rushing water off trail and hiked a quarter mile up the stream to find some beautiful waterfalls.  I may have fallen in up to my knees and slid down a muddy hillside to get there, but it was worth it.
