My favorite place in the entire world is Wissahickon Creek Park, just a 10 minute drive from center City Philadelphia. When I was a young boy, my grandmother took my sisters and I to feed the creek's ducks loaf after loaf of Wonder bread. And when lived off campus during college, I was able to mountain bike right out of my back door on those same trails, rekindling all my early memories of the park with every pedal stroke. Ten years down the road, when I got invited to a Facebook group for city-dwellers looking to do outdoorsy activities, I made their logo before they even asked for one. Lo and behold they were thrilled, as was I. #outsideisfree
