At the same time and place they are having the mid atlantic top prospects showcase, which it says you can ask for an invite:

Top right click on Pennsylvania.  Good luck.

Sportsmom: I know you mentioned 3 hrs drive and Philly is 300 miles. But the University of Penn Camp takes place September 18-20. In addition to Penn, (according to the site) coaches from the following schools will be working the camp - Swarthmore, Ursinus, Tufts, Bates, Bard, and Elmira. You did mention an academic showcase (camp).

You'll find that the vast majority of showcases in Northeast  (3 hr radius from you) have wound down for calendar year (due to weather). The exception would be college camps. Good luck!
