A Montgomery, WV policeman had a perfect spot to watch for speeders, but wasn't getting many. Then he discovered the problem - a 12-year-old boy was standing up the road with a hand painted sign, which read "RADAR TRAP AHEAD". The officer then found a young accomplice down the road with a sign reading "TIPS" and a bucket full of money. (And we used to just sell lemonade!)

Now that's free enterprise at it's finest.
