Both Waynesboro and Greencastle are being overrun with sprawl development. Washington Twp around Waynesboro is probably addressing development issues a little better, much to the chagrin of the developers I used to represent.

Waynesboro is also closer to the green hills of the Michaux State Forest which is a miles-wide swath around the Appalachian Trail. Greencastle is out in the middle of the valley closer to the highway. I don't really know the schools well, there had been a couple of posters in that area so maybe the bump will encourage them to take a look.
