A Chemistry Prof of mine years ago told this tale. He was part of a regular golf foursome, playng a round on a bad-weather day on their regular course. One hole had the green behind a small hill, so it was fitted with a very tall (about 25 feet) flag pin you could see over the hill. As their party was holing out, he suddenly realized he was standing in the middle of a flat open space in an oncoming thinderstorm, and holding erect a 25 foot steel pole while his friend putted. That's when they decided to quit for the day. These ones survived!
