Once I visited a home of a happy farmer in Florida. But when he purchased his farm in the first place, he was nearly driven to despair.
Earth was unsuitable to grow any kind of crops. It was impossible to grow vegetables or raise pigs. On the site grew only holm oaks and rattlesnakes were carried out. But eventually it dawned upon him. What if we make minuses into pluses? Why not to take advantage of rattlesnakes?
To everyone's surprise, he started canning rattlesnakes’ meat. Several years ago, I stopped at a farm and learned that the crowds of tourists wanted to see the rattlesnakes` farm. It was annually visited by twenty thousand people. His company flourished. Poison extracted from the teeth of snakes, was sent to the laboratory and was used for the manufacture of antitoxic immune serum. The skin of snakes was sold for a fabulous price. Women's shoes and handbags were made from it. I saw the canned rattlesnakes` meat dispatched to customers worldwide. I bought a postcard of the farm and sent it to the village post office, which was renamed and called "Rattlesnake", in honor of the man who turned poisonous lemon into sweet lemonade.</quote>
