Ok... here are my top 5, in no particular order:
Jordan Creek, Whitehall, PA
Tyler State Park, Newtown, PA
Maple Hill, Leicester, MA
Borderland State Park, N. Easton, MA
Tinicum Park, Erwinna, PA
Close 6th: South Mountain, Bethlehem, PA (the course that intorduced me to a lifetime of misery as a rec dg player)
