Before my camera was stolen, I did some photography in Princeton or Lambertville. Nice array of architecture, lots of people doing interesting things, etc. Did New Brunswick a few times, too. Other times I would find abandoned buildings and shoot those, but that is a highly local thing.
I'm actually an awful art photographer, really all I can do is action stuff so I have no good suggestions.
Las Vegas is my favorite place to take pictures, everything is awesome looking with spectacular and strange lighting.
