Robert,
I remember a field being close by with a paved runway. I don't know if anyone flys jets there or not. I believe it was in Hecksher State Park just to the SW of ISP
an I think it was the SE corner of the park but may be wrong.

Maybe someone knows more about it. I am pretty sure that is where it was but that was about 8-10 years ago.
