Four years ago, I had a horrible nights sleep because 4 bulls kept bugling behind my camping trailer. The next morning, I killed one of them and had a 300 yard pack to the trailer. One of the best ruts I've ever hunted and there was no one else there. The elk moved in after opening week, and the "hunters" thought the area was bare.
My mother has shot several deer and elk while she waited for us in the truck. If she didn't feel like hiking that day, she would sit in the truck and read a book while we were hunting for the morning or evening. They would cross the road, she would sneak on them, and then we would get back and pack it out. She is also hell on grouse.
Other areas I hunt require a trek across poor habitat to the good habitat. My take is simple. For the rut, know where the best food is, and hunt there regardless of distance from a road. For late season, hunt as high as the snow will let the bulls feed. That might be at the top, or it might be much lower. If you want cows, or any legal elk, hunt the food.
