There are probably not enough interested owners just in NY. Possibly a Northeast Group could flourish. New England, NY, NJ & PA should have enough owners. If someone wants to start an unofficial group to be a link for regional meets and shared interests, maybe a Facebook page would help.
I am an ex New Yorker and I visit the state every Summer to enjoy the area. A great possible place for a Summer meet is in the Catskills. It's called Peaceful Valley Campground, and is very easy to get to because it's close to Rt. 17. I have stayed there every August since 2009 and there is always extra room for folks without reservations. If you like fishing, hiking, or biking you should really enjoy the area.
