Kind of hard to believe the frost is down 5 feet already!? I think thats a bit of a stretch. I know its going down, we only have about 2 inches of snow on the ground over on the west side of the state and the above zero days have been pretty scarce since Christmas, but I really don't believe its down 5 feet....at least yet and for sure not in the woods. Another 2 solid weeks of this and it would be believable, but from what I hear temps are forecast to moderate.
