Replica Bomb Crater
Boise City, Oklahoma
In 1943 Boise City was mistakenly bombed by a training mission from an air base in Texas. The only thing destroyed was a garage -- doubly embarrassing for the air force, since the bombs were aimed at the courthouse. Most towns would try to forget this kind of thing, but not Boise City. In 1993, on the 50th anniversary of the mishap, the town built a replica bomb crater out of concrete and placed it in front of its chamber of commerce office, which is an old caboose.
One of the bombs that fell juts out of the crater, and in front stands a plaque: "Boise City -- Still Booming." The crater is less than 2 feet deep.
