Riding a metric century (100Km from Reston out to Purcellville and back) on the W&OD bike trail while playing with new GoPro camera. 150:1 time compression (do you really want to watch this in real time?). See if you can find the five crossings against the light, four pasing discussions, three creature encounters, two tunnels traversed, and an increment to the cycle critter carnage count.
