Excellent idea.
I'm in NYC - Upper West Side. There's a LF group meeting regularly in Massachusetts, but that's a 4 hour drive and a litte far for me. To my amazement, there does not seem to be a LF group (or medium format for that matter) in NYC. I'd be happy to join. Can I suggest Central Park? There are plenty photo ops and also places to sit down and meet. I would also suggest not to limit attendance to LF'ers, but to anyone interested.
