Plenty of chances to lose coins in the first place, because gravity works and lots of us handle change. I know that. But then something hit me: you rarely find coins on residential sidewalks, yes because people aren't around as many businesses or other opportunities to buy stuff but also because plenty of people pass through, keeping moving. You're more likely to find coins in the middle of a street, never mind how they got there in the first place.
You're most likely to find coins in places people pass through. Places where people go and don't stay.
Something about thinking that made me a little sad.
