Someone will mistakenly think I'm implying that astronauts are messy. Not. I am coming right out and saying that some people are slobs. Hiking in a scenic place and coming across detritus from a junk food binge really is a nature-buzzkill. Don't get me started on people who throw trash from their cars because they want to keep their ride clean.
Can it REALLY be possible that some people don't know better? How sad. What if people really DO know better? Beyond sad.
