Consider a Ghost Walk Tour.
They're usually in the evening, when it's cooler, you walk, and they take you to various locations where they narate a Ghost Story. I know, it sounds kind of ho-hum but it's a nice secure evening walk, has some entertainment value and considering the cities history, you may learn something. The stories are "legends" not like the para-normal crap you see on TV!
So far, we have been taken these in: Alexandria VA., Savannah, Charleston, Williamsburg & Yorktown VA. We don't "believe" in ghosts but, they can be entertaining, and a good way to walk off your dinner.
No doubt it could be dome in Buffalo but the size of the city would make it difficult to walk to all the various sites. Enjoy Charleston!
