I'm in NJ about 15 mins from Philly. Haven't seen many other SOHC bikes around and don't know of any get togethers. One fellow at cruise night has a bobbed out SOHC4, another has a DOHC CB750 (1980 maybe?). I've seena few 70's twins around but never stopped and met anyone. I'd be happy to meet up or try to get a few of us together at some point over the summer.
