Check out temperature on this trail photo

It finally warmed up and snowed a bit so Cork and I beat it to the back 40 to pick up our trail camera cards. We hadn't checked them in two weeks. The most interesting thing was that the trail cameras worked at all during the bitter cold. In the case of the Bushnell Trophy Cam shot above, I believe the manufacturer says it will work as low as -20 C. Obviously, it worked in far colder conditions. I use lithium batteries in all my cameras.
