What I do know about Frick's Lock is that it's about 250 years old, and its heyday was long behind when PECO bought the homes in the 1970s. Supposedly, Frick's was an unsafe place to live with the Limerick power plant right across the river. There was talk of restoring the town into a historic site, but with (very) recent vandalism, Frick's Lock could end up like Demon's Alley -- completely demolished.
