Dr. Strangebike dismounts. Where could we be?
Hmmm... lots of concrete and steel plate.
It's a batting cage in Richboro, PA. But wait, it used to b a Nike missile site - specifically, Nike site PH07A
Here's what it used to look like: the elevator leads to an underground complex. According to Wikipedia, Nikes were SAMs located in a small batteries around cities/ targets to defend against Russian bombers in the 50's and 60's. PH07A was one of several batteries that defended Philadelphia.
It's not obvious why someone chose to put a fence around just a section of each elevator.
The site now sits in the center of a suburban sports complex. You can't fling a dead cat in any direction without biffing a soccer mom, her mini van, or her screeching progeny.
HIT THE BUTTON!!! SOMEBODY, HIT THE BUTTON!!!! LAUNCH, LAUNCH, LAUNCH!!!
The ride home involved getting stuck in New Hope traffic and an accidental incursion into New Jersey.
