Drawing a tag for Unit 4A offers outstanding opportunities for whitetail deer hunting. Most of the unit consists of rugged badlands, with steep, narrow canyons and densely wooded creek bottoms. The Little Missouri River flows through the heart of the unit, supporting a lush deciduous forest along its banks. If you can find a prime hunting location near Theodore Roosevelt National Park and patiently wait for a deer to venture off the park’s land and onto huntable property, you may have a chance at a Boone & Crockett trophy.
