I just got back from a drive along Michigan's I-69 between Flint and Marshall - a round trip distance of approximately 180 miles. I counted 37 deer carcasses along the sides of the highway - all within 50 feet of the road. I didn't count any twice and I'm sure I missed some. In some places, the snow was too deep to see, and some of those miles was near larger cities (Flint and Lansing). So if we make it 160 miles of rural terrain, that comes out to 1 dead deer every 4.3 miles.
How does that compare with what you usually see in your area?
