Wissahikon X-country biking (again)

阿福羅萬歲！好久沒有這種人車一體的感覺了！

I've always thought the best way to use a sunny day in Philly is to go cross-country cycling on one of the many offroad trails in Fairmount park's Wissahikon valley. You get all the fun, the excitement, the needed exercise, the fresh air, and might stumble upon some good photo shots along the way. Only issue is that offroad trails burn through tires and break pad faster, but the fun makes up for that. The Wissahikon trails are actually neatly managed, and the bikers are overall quite friendly.
