Kayaking on the Charles River

Last night after work went kayaking on the Charles River with buddy Vin. Another great workout, and I definately can use more upper body workouts. Kayaking isn't quite a replacement for swimming but at least I'm getting closer to the water...! We were out there for 1h50m covering an estimated 8 miles up and back part of the river. Not bad, and I wasn't even sore the next morning.
