On hot days an ice cream truck makes his rounds around the playground here, and when it comes along the streets it plays a melody, so you can hear it coming. I think this is somehow nice. When I was a kid, a very old guy came in his little truck and he was selling potatoes. We called him "Kartoffelmann", and he always sounded a big bell and screamed "Fresh potatoes" and the neighbors would come to the street to buy potatoes. I think this has pretty much died out, like the milk man. So I enjoy the ice cream truck and consider it a reminder of old times.
