Recycle It: Through a Junkyard
It might come as a surprise that junkyards are often willing to take old items -- especially stuff that is metallic in nature -- and give you cash in return. Even stuff that garage sale perusers and neighborhood curb sharks might turn their noses up at!
If you have a car that's been slowly sinking into the grass in your side yard for years because it doesn't run anymore, check with your local junkyard because chances are, not only will someone pick it up, they'll pay you for the chance. Other seemingly worthless items -- say bent fencing, rusted lawn furniture, a beat-up barbecue grill, an old air conditioner, decrepit bed frames, leftover wiring -- still have inherent value, as long as you make the effort to get what they're worth.
