I'm sure we'd all love to have you dive with us, and participate in New England diving discussions, but as mshieldsdunn and Spectre have said, the point of having the regional group is to foster comradery and participation, and to give us a forum to discuss local sites, experiences, and issues.
How often would you be likely to come up to Cape Ann for an after-work night dive? How would you feel about meeting in Maine, Cape Cod, or Block Island on a given saturday morning?
Does that sound like a local activity, or a road trip?
If you think you'd be able to be an active New England Diver from New York or New Jersey, that's great, and I hope to see you, but it sounds like a long way to travel regularly.
Again, I think we'd all be happy to have any of you from outside the area join us (in the water or the forums) anytime, but I don't think expanding the New England region would add any real value, especially since you can jump on the board and chat with us, or join us for a trip whenever it's convenient for you without having to do that.
