Temperature hasn't been above freezing since Monday, and most nights have been in the single digits. Still walking in the park every day though.
In the center of the picture above, the Canada Geese are swimming in a circular area of unfrozen water. Below is a better view of that area. A few days ago the surface was completely frozen over, and I'm uncertain about what caused this part to open up. It hasn't been because of any warming trend because there hasn't been one.
