Swiss Tradition: Hacking Duty

Learned about a Swiss fall tradition this morning, Häckseldienst aka Hacking Duty. You can sign up to trim the trees on the streets so that they meet very specific requirements in terms of how tall they can be, how much they can stick into the street, and how much light they can let in. Sounds like a great way to get some exercise, let off some steam, and mix with your neighbors.
