It's "Hockey Day Minnesota" today. Basically a bunch of high school teams, and a few select college teams, play in games all day at a select city outdoors. This year is in Bemidji, MN, on a lake.
This morning, when the puck dropped for two HS teams, Minnetonka and Andover, it was -30F (-34C). Yikes!
However, it's fun to watch from your 70F living room.
