Though I prefer big game, I really like chasing upland birds/small game as well. For me, the best state that I've found is Idaho. In any given year you can hunt whitetail, mule deer, pronghorn, elk, and black bear OTC. Upland birds include 5 species of grouse, plus huns, chukar, quail, and pheasants. My ideal location would be somewhere in the south central part of the state. A good second would be the Salmon/Challis country.
Where did you find an OTC antelope tag?
Most of the elk tags in the south central area are by draw. The OTC elk are farther north.
