Wisconsin residents push an entire island with boats to clear a passage under the bridge. At Lake Chippewa in the US state of Wisconsin, locals regularly take boats to remove huge floating peat bogs from a bridge. These "islands" were created from marshland that sank after the creation of the reservoir in 1923, and over time trees grew on them that act as sails and move the mass with the wind. When such a peat bog washes onto a single bridge, it effectively blocks the passage between the two parts of the lake. The island cannot be destroyed or cut - it is a protected habitat, so the residents gather on dozens of boats and work together to push it out into the open water. It happens almost every year.
