I assume you are way ahead of me, although I've never made an effort in this area. I would guess maybe 2 (NH and CT), although I've certainly been close to RI on many occasions, just never left the pavement there.
Ahead of me too, I think my list is MA, NH, CO, and CA.
Uh, Peter, I think you also have SD.
That's exactly what I need, a substitute memory. I wonder if there are any others I've done? Don't think so.
