There are a lot of people who don't understand what ice shoves are if they don't live close to water. We do in Oshkosh. Even though the weather has been getting better (somewhat), there is a still A LOT of ice to melt. The shoves are created when there are currents in the water (the open portion), temperature changes, and wind. I LOVE this pic of Caden from when we were still on our cruise:
Here is a video of some ice shoves coming in from Lake Winnebago. This is right in Neenah, about 15 minutes away. Crazy stuff.
