The cans are recyclable up here in CT, so that's at least another .15 in clad.
It's frozen up here, well now it's raining like crazy, but a couple days ago I walked around at the highschool, found .61 clad, and picked up a pocket full of small trash. I won't have to remove it later with my detector. It still amazes me that people drop their garbage like the world is their trashcan. Ever since the Indian on the side of the highway crying....I'm aging myself.
