"One man's trash is another man's treasure," you've heard it said, and you take this saying to heart each night under cover of darkness at the junkyard.You never know when you'll find that piece that will complete someone's collection, and you never know when you'll have to leave empty-handed. If you know how your fellow Dumpster divers operate, you just might be able to score big in the junkyard. So grab your burglaring gloves, backpack, bike, motorcycle, car, or truck and see if you can discover some unexpected treasures.
