When I saw this on the way to work the other day I was kind of shocked. Who cares enough about their trash to put a sign that says keep out. It's trash. The end goal is to get rid of it. Why should they care if someone takes it? I see a couple good bike tires there. But when it came to caption this image, I couldn't think of the best one:
"How will the garbage man take it away?"
"Why the smily face; is it a joke? Am I not supposed to keep out?"
"What's so good about your trash that I can't have any?"
"What's so dangerous about your trash that I can't have any?"
"Is the sign trash? If I take the sign, that's technically keeping out, but then others may keep in."
