Skydiving
Ole was to learn skydiving. He was told that shortly after jumping out of the plane he was to pull the short rip cord and that will open a small parachute which will open the large chute and if by chance the large chute fails to open, he should pull the other cord which will open the large parachute. He was told that a car will be on the ground to take him back to the airport.
Ole jumps out of the plane and proceeds to pull the first cord. The small chute doesn't open so he pulls the last cord and the large parachute doesn't open either. Ole thinks to himself, "It will be just my luck that the car won't be there either"

Garnet CarterDied 21 Jul 1954 at age 71 (born 9 Feb 1883).American inventor of miniature golf. In 1926, Garnet Carter opened the first miniature golf course at the Fairyland Club on Lookout Mountain. To his surprise the course was taken over by adults, who liked the fantasy setting and enjoyed the challenge of putting a ball through the miniaturized fairways. Carter soon began manufacturing courses for national distribution under the patented name Tom Thumb Golf to continue with the fairyland theme of elves and gnomes. By 1930 there were over 25,000 miniature golf courses in the U.S. In 1932, he sold the rights, and with his wife used the profits to open Frieda's Rock City Gardens. By 1940, Rock City was a roadside institution. "See Rock City," was painted on barns and birdhouses throughout the Southeast. |
