Heard of the joggling board? These bizarre local devices date back to the early 1830s, designed by Mrs. Benjamin Kinloch Huger as a mild form of exercise for her rheumatism (the board allows you to bounce, gently, on the spot). It’s essentially a long plank of wood supported by two struts, which bends (but doesn’t break) when you sit on it. Kids love them. This company revived the old art in 1970.
