So parents, be on the lookout. You can prevent some bad stuff going down pretty easily with just a watchful eye. Heck, you might even want to tell the older kids about some of these signs - not to scare them, but to let them tell themselves when it's probably a good idea to come inside and get warm.
Maybe these will give you and the kids something fun to do...AFTER you rebuild your snowman. Oh, and if you run out of snow, you can always come to my house to get some more! Free of charge, even!
