Near the end of my "shift" I was disappointed I hadn't found a can yet among the rotted shelves, rusted tools and dust-covered boxes and containers. And then I pulled up some old wooden stakes and I found a stash of eight dirty cans. The problem was, they had all been crushed after the person drank them. All of them were aluminum and the ones I could recognize were relatively newer cans that I already have anyway. A couple of the cans were so crushed I don't know what brand they were.
So what could have been a great can find turned out to be a bust... until my dad came over this evening and said he found this "rooster can" while on his daily walk the other day.
So I did end up with a treasure today after all.
