That's not what I'd understand as a "ring" though. I guess something like that could be useful in providing an alternative to what's mostly been car options for travel between Brooklyn and Queens. Edit - your more ambitious idea could be a "ring", yes, but I'm not seeing how it would be especially useful. Why would it be helpful to provide a single line allowing someone in Bayonne to get to Jackson Heights, for example (given what are probably more pressing transportation improvement needs)? As a visionary means of facilitating a longer term integration of eastern New Jersey communities to New York City, maybe.
