Ben, Access is a touchy issue around here. As well it should be. There have been stories of abuses in the past, so finding help may be a little difficult, here. Not that people don't want to help, they love meeting new people from all over the world. With that said, hopefully I can be wrong and you will get the access you need on the east coast. If not, I'd recommend the west coast. More public access course, better weather.
Perhaps if you describe what it is you like about golf architecture, people can mold their recommendations to your interests If however, you just want to play "name" courses, it may be problematic.
