CP Potter (residents always called it "Potters Crossing" in the old days) is on Iman Avenue in Edison. Its on the northern Edison border, right where Middlesex County and Union County meet. Very close to the Scotch Plains border. Its also about a 15 minute drive East of the Raritan Valley line, with Fanwood being pretty much directly West of that spot. If one was coming from the GSParkway, you'd get off at exit 131 onto Rt27 south, follow Wood Ave up the hill for three traffic lights (its a couple/few miles) and make a left onto Inman Ave. Its then about a 2 or 3 mile drive to the crossing.
That area used to be almost all woods, but there has been substantial development right along the mainline, especially on the West side. The East side still has a lot of trees and I believe is county land. I used to hike along the mainline from Inman Ave to the golf course (and beyond). I stayed to the side of course, NEVER on the tracks, even as a kid I knew better.
Its hilarious to hear the locals complaining. They buy a townhouse that is RIGHT ON THE ACTIVE MAINLINE, for all intents and purposes, then they complain that there are trains going through. Kind of a "duh" scenario.... I think some of the condos actually have a nice "view" of the tracks. I'd be out there with my tripod set up all day - never even have to leave my balcony!
