I hunt in the bluff country of SE MN, so I had a difficult time before I “really” figured out the rabbits in this area.
I try to hunt both public/private, near fence lines, brush piles, old farms/equipment, etc. I also just got my first pup, a german shorthair, who points on rabbits/pheasant/grouse and does not flush or chase!
More west is your best bet for bunnies.
