The deeper lakes around here (100 feet or better) remain open, whereas the shallower ones have frozen over. I noted some kids ice skating this last Saturday on one and some ice fishermen out on a couple yesterday. Tis the season.
Best to send the model out ahead of you to test the ice however. Make sure she leaves her clothes on shore where she will be able to slip into something dry should she fall through. Also make sure she stomps her feet to test for weak spots you should avoid when you venture out.
