Okay. Let's clarify the geography: Running south to north (generally) you have Roxborough Ave., Cotton Street, Grape Street, Monastery Ave. and Lyceum Ave., in that order. Crossing these, going east to west (which means from the Ridge Avenue side headed towards Main Street) are Manayunk Ave., Dexter St., Fleming St., Terrace St. and Boone St. Then the hill, and down to 19127. In other words, we're talking just a handful of square blocks. Concerning drugs and trouble, it's like a stone dropped in a pool of water: Fleming at Cotton is where the stone hits, and the ripples go outward, diminishing as they go.
