I prefer the hills. The flat land has mostly been burned over. No cover for coyotes or you. You get seen from a mile out your busted and don’t know it. Less he does a warning bark.
The hills you can make your approach over a ridge ,get settled, and not be visible to the country your calling to for very long.
Problem west of there the land trust, nature conservancy, has bought up big tracts of land. Fancy fences and all posted. Says hunting by permission, but I’ve never heard of anybody being granted permission.
I always say, thermalists out, that 85% of the coyotes have nothing to fear from 85% of hunters. Go test your mettle.
