According to the local news radio station:
Bucks County is the focus of world wide interest in unidentified flying object sightings. That’s according to local UFO enthusiasts who meet monthly in Philadelphia’s Fishtown section.
Bob Gardner is state section director of the Mutual UFO Network — or MUFON. He’s an expert on the Bucks County UFO sightings and a regular attendee of the UFO discussion group at the Germ bookshop on Frankford Avenue.
I think I know who they may be looking for.
