Closer, cheaper tags for non residents, more public land, lots of 4wheeler friendly land, a good draw system, and better all around opportunity for a trophy with an OTC tag. Montana has a lot of areas for big bulls, but very few are OTC. They do have great elk numbers, but you would be hard pressed to find areas that are OTC and able to pull a mid 300 inch bull out of it, with any consistency. They do have them, but not like Idaho
