With Dickinson and the law school pretty much closed for the summer, Carlisle will be a bit slower than usual, but there are things to do in town, plus Gettysburg is not far away. If you have a car, DC, Baltimore and Philly are each a bit more than 2 hours distant. HersheyPark is less than an hour away.

If you are into the outdoors, plenty to do. Lots of open space with hiking trails. A big lake is not far off.
