Ed:
Good shooting! Always a pleasure to read your hunting posts. Wish I had your gift of patience and stealth. I fear I am not much of a hunter when it comes to sitting still for long periods in any kind of cold weather.
I haven't noticed any fox squirrels in the mountains of WNC -- only gray Squirrels, but then I am not an avid squirrel hunter, and they may be out there. But I have seen, on one or two occasions within the last several years, a rare critter peculiar to this region (my mountain place is about 6 miles E by SE from Brevard, just across the state line in NC). A white squirrel! If I ever get a shot at one, I don't think that I will take it, though, except maybe with a camera. The local white squirrels are not albinos, as I understand, but a variation on the coloration of the eastern gray squirrel. Daughter Laura says they live in Davidson, NC, too -- where she went to college.
