Not exactly in South Carolina, but on my stopover in Atlanta, Georgia at 6am one morning, I stood on the overpass of a highway next to the Amtrak station and heard the traffic ooze by. The red and white lights of the vehicles moving all around me were beautiful, unending, and putting a consistent 83dB into the air.
Small souvenir bells in Charleston were sold in shops. Small china figures shaped like African-American house servants from days gone by. They were common in the shops.
Inside the the trolley in Charleston, it was very rumbly. Compared to the New Orleans streetcar, this was painful.
