Try LVRCS.com, buc-le.org and tcws.org. I think the LVRCS (Lehigh Valley Radio Control Society) would be closest of the three. Buc-Le and Tri County Wingsnappers are the two nicest of the three with Buc-Le having the longest, widest runway (about 1000 feet) and Wingsnappers has a smoother grass runway and a kitchen. But Wingsnappers is the furthest at 60 miles from Stroudsburg, Buc-Le is in the middle at 52 miles and LVRCS is about 30 miles.

I live in Macungie, PA and drive 22 miles to Wingsnappers and sometimes go to Buc-Le which is 14 miles for me.

Best of luck,
