As mentioned previously, Llanerch has some blocks that are worse than others, near the diner. Near the Kirklyn section of UD, specifically.

Westwood Park, near the LA Fitness on West Chester Pike, is hit-or-miss.

There are also some questionable areas off Darby Road, near the intersections of both Eagle Road and Manoa Road, and a little stretch of Lawrence Road, near Lynwood Elementary.

Westgate Park is nice. Chatham is nice. Bon Air is nice.
