5/4/2004: Sinkhole eats car

I think what got 202 wasn't an ordinary sinkhole but a limestone fault -- basically a huge mucking crack in the bedrock, like a cave only filled with soil. Put any weight on it, or disturb it too much, and the soil moves out, creating sinkholes.

There certainly are plenty of ordinary sinkholes in the area -- N. Gulph Road had a number of them caused by an underground stream, and the K.O.P mall has had them appear in it's parking lot.
