Snow caves! Hadn't thought of that in a while. After the storm in 2016, our parking lot had snow piles over 10 feet tall. The neighborhood kids built an extensive complex of tunnels in the biggest pile. It was truly impressive. I had to make some of them a bit larger, so I could fit in!
I was just at the Cabin John rink last week teaching my youngest to skate. He was terrified to try, but picked it up in 5 minutes. Now all he wants to do is go skating. The rink looks nice. They just finished up a big renovation. It still smells like dank sweaty socks, though...
