I am one that beleive we do not see all the elk or deer in all the areas that they are, both summer and winter range. Some of the winter ranges are easier to find and see MOST of the animals but I don't think that anyone see's all of them, especially if you want to think of a whole state, Like Utah or Ax. As mentioned by others in this post, if a person has flown any of the remote area's of any western state, you can not see all the game in the area, let alone the state. I fly all summer looking for marijuana gardens in the county in live in California which is about 4000 sq. miles. I will fly for a week straight to find gardens then go rip them off. In 4 months, I can not completely cover the entire county and that is looking for something static, looking for animals or people is even harder. Yea, I get to see lots of game, but not even close to what is actually out their. I have flown on many gardens, seeing several deer, elk pigs or bears, then set down 1/2 mile away then hike in to raid the garden and see even more animals that we didn't see from the air. As far as dope goes, we figure that we find about %50 of the gardens that are actually their, so I think animals would be even less. One thing is for sure, from the air, their is a whole lot of country out here that just goes on and on almost forever. Even here in Ca., most think this state is populated, but try flying it and you will be amazed at how remote a person can get anywhere in the west.
