This was my daughter-inlaw's idea, so my wife and I went along with it. Let's face it,it is almost obligatory if you're in Charleston, and you are a tourist, you need to take a ghost tour.
There are so many of these little tours every evening that finding one won't be difficult. Discount coupons are available all over town to virtually all of these tours, but really aren't really necessary as they pass them out at the shop where the tours originate.
The tour I took was probably as good as any. They made sure to walk you by some of the cemetaries on Church Street and some of the haunted restaurants. The ghost detector they passed out was a hoaky touch. I'm glad I did this once, but would not bother again.
