18.5 miles each way. Riding from south Philadelphia to the northeast part of the city. Today was my on my Panasonic DX-4000 and tomorrow I'm toying with the notion of riding my Stella fixed gear conversion. Al least once this summer I'm going to do a different bike each day: Panasonic road bike, fixed gear, 1965 Schwinn tandem, Specialized mountainbike, I guess motorcycle on Friday.
