Trip to Long Island

I'm visiting Long Island on a business trip on 21st
June and not flying back to the UK until the 24th,
so I've emailed the Long Island Soaring Association
with a view to spending Saturday 23rd with them. The
thing is, I've not had a reply . . . so does anyone
know if:

a) they're still in existence?
b) they're happy to accept visiting glider pilots from
the UK?
c) have an alternative email address I can use?

Thanks in anticipation
Steve
