Great idea NH. My partner always says that whenever he hits traffic he gets into the left lane and scans the shoulders and medians for scrap. He said one day he found three wallets, 2 cellphones and a 9mm. He contacted the owners of the wallets and the local pd for the 9mm. Cellphones were crushed so those got recycled. Cleaning up a bit of the roadway can also be a treasure hunt at the same time.
