A few days ago on my regular walk through a forest reserve I found two unopened cans of a popular alcoholic beverage. Just lying there in the cold air, with dew all over them. I moved them with my foot and they were intact. That was a jarring reaction I had. In the woods. Beautiful day. No one around. Full cold cans. Two wouldn't hurt me. I left them, thinking someone would be back and drink them. After all they weren't mine and people do all kinds of geo-caching and other things these days. What do I know?
A couple days later they were still there and then I saw them as litter. Dangerous litter that some little kid might find. I used the pointed end of my umbrella and poked holes in them (maybe a bit too forcefully!) The first one kind of exploded and I could smell it.
I made sure they were drained. The next day I returned with a trash bag. I didn't want to touch them or smell them so I picked them up with a stick. Garbage deposited in bin. Take that, stoopid AV.
