A friend has an intruder-catching IR camera set up in his back yard. Last night it produced a video of a possum moseying across the yard - and falling snow as well. This was at 10PM on the 17th of January, temp in the low 20s, in Vermont. Shouldn't that beastie be hibernating? The occasional possum has been showing up for the past decade or more, but us hillbillies still ain't apt to even know what they're seeing, certainly don't know their lifestyle.
