Everytime I see a garbage receptacle I have have mixed feelings. There's a good feeling that garbage is being taken care of, but the fact that they are needed everywhere dismays me. I'm sure parks puts garbage cans wherever tossed garbage is a problem, but the fact that it can become a problem is the problem. The result? Hundreds of garbage cans everywhere, they themselves littering the landscape like the garbage they contain.
But without them, the problem of strewn garbage would be unmanagable. So bring them on!
