That would be sweet. Nice Rambo reference. You know that train bridge you see off the George Washington bridge on rt 195? That's part of the same old abandoned train line.
yeah, going down the bus tunnel is a great way to get either killed or heavily fined. however, there's some old tunnels near the train station that a few RISD students filled with mannequins splattered with red paint and in torturous poses. pretty fun to check out.
