While walking the dog last Monday I found a spruce tree blow-down that had lots of lichen on it, so I set up a camera. Well it warmed up to -26 today so I went to see if it was frozen up. It took my pic when I arrived so it was still functioning, even though temps were in the low -30's for a few days. Because of poor placement, I got a lot of ear tips and tails, but a few deer. I will reposition it tommorrow.
