Apollo Moonprints in Cement
Myrtle Beach, South Carolina
In April 1972, Charles Duke became the 10th (and youngest) man to walk on the moon. He was a South Carolina boy, and 10 months after his walk he became the first member of the South Carolina Hall of Fame. At his induction in Myrtle Beach, he donned moon boots and left two footprints in the middle of a slab of wet cement.
The moonprints remain, surprisingly pristine, in front of the Myrtle Beach Convention Center. Although they've been outdoors all of these years, there's no chance of frost damage, and the slab is far enough out of the way of foot traffic to discourage any gum wads or cigarette butts. Placing your feet in the moonprints is not encouraged, and might be very uncomfortable in Earth's gravity.
