I saw that video earlier, I think that's the first time that I've seen a can with a pull-tab which someone churchkeyed anyway. I wonder what that was about. Also, what was the broken milk bottle you found? That looked like it was older than a lot of the other stuff you're finding there. I wonder if there's an older layer underneath all the sodas. Also, those bottles which say "Not to be refilled" are American (I think) NDNR beer bottles. Never seen them used in Canada.
