Hunt along the edges of the hardwoods and creeks. Edges are a funnell sort of speaking. Anyplace that restricts deer movement, ditches, creeks, ponds wide open fields will divert deer.Topos would seem pretty useless to me in a lot of the midwest. It's so flat that the countour lines would be non existant almost. The best contour finder/ pinch point finders'/funnell findersin such a case are binos, rubber time and feet.
