The Schuykil River runs through Fairmount Park in Philadelphia. Colleges meet here on the banks for rowing competition and training, which I used to watch on my daily skate. One of the best paths for skating in Philadelphia is a bike trail that runs 8 miles along this river.
One of the more liesurely preoccupations is fishing, though I don't kow what catch is desired. I am sure the fish will be as impressed as I am with her outfit.
