The theatre is located in Exton, Pennsylvania, about 20 miles due west of Philadelphia. It's on Rt 100, just north of the junction with Rt 30. It's between the Malvern Federal Savings (a big, white, colonial building with columns that's flood lit all night) and a Kmart (that will probably be dark). It's directly across the street from Whiteland Mall. If you want to use a roadmap engine (ie Lycos Roadmaps), the street address is "173 Pottstown Pike, Exton, PA, 19341".
Here are some directions. Most of them havn't been tested too well, so use some common sense. If there are any errors, please email me.
