I hunt about 20 miles east of 81. We kill alot of snows every year. The number gets smaller every year. Part of that reason is I dont get out a much as I did before I was married and had kids, the other part is they are getting smarther than ever. Good luck, if you are in the area around Fairbury or any parts east or south give me a yell.
Dont shoot where they have been, shoot where they are going.
