We visited my son there when he was in training to be a navy nuke. It is a very pretty place. With a few alligators. Incidentally, the students are prohibited from feeding the alligators.
It was the only thing of beauty on that Amtrak trip; everything else about that train ride was squalid and depressing.
Charleston is a great place though. We went there because we were looking for a conservative destination - wanted out to spend our vacation $$$ in a Red State.
