Welcome to TranBoard! Been to Charleston, SC a few times, but I don't know the area well enough to railfan it. Lots to see I'll bet. If you want to see some exceptionally cool ACL and SAL photos, visit the John Barriger Library photo collection at: https://www.flickr.com/photos/barrigerlibrary/albums/with/72157640460358816 There are albums of many different railroad albums there, all from an era long since passed. You have to click on a photo to find more about it. A number of people (me included) have helped to identify where photos were taken and there's good discussion too. WARNING: the site is addictive and you'll spend days there.
