Just curious.  A lot of providers, local and touring, seem to operate out of King of Prussia.,  Why there?

It has the second largest mall in the US and many upscale hotels.

Very accessible by interstates from Philadelphia, New Jersey, Delaware and even NYC.

Just be careful. Not sure bout now but it used to be called Cop of Prussia. I remember a member on here saying the hotels worked with the cops and set up the ladies.
