Dale Rooks a crossing guard at Suter Elementary School in Pensacola, Florida had tried for years to find something to get drivers to slow down in front of the school -- including waving his hands and yelling -- but nothing worked. Then inspiration struck him -- he got an old hair dryer and covered it with gray duct tape so that it looked like a radar gun, and started pointing it at speeders. That did the trick. People are slowing down, raising their hands at me apologetically, " he says "It's amazing how well it works." Inspired by his example, fifth-graders at the school set up a lemonade stand and raised $93 to buy Rooks a real radar gun. "I don't mean it to be funny," he says, "but it looks just like a hair dryer."
