Stripes of snow, sand, ice, and rocks on the beach. The water, by the way, had no ice on it at all. It was quite wavy, which meant we had to watch our feet constantly. There are few things I like less than having wet feet in the winter when you're stuck outside.
This last is not at IL beach, but in my mom's yard, where some squirrels have dug at least 15 holes such as this right in the grass, presumably in search of there caches. It should make for a lovely lawn in the spring... oh, well!
