Does anyone go up to Cape Cod, MA to catch a flight?

I do, but I normally wait for coastal storms so I can bring heavy stuff to make it worth the trip.

Does anyone know of any slope soaring spots on long Island N.Y...

There are some locations near Sunken Meadow Park, at the top of The Sagtikos Parkway ( Exit 53 north on LIE). Responded to your other thread.
