Nobull,
You are getting some good advice here... Stick with your unit, go further, hunt harder/smarter and figure out where the elk are at, when they are there and why. If you are finding sign it is just a matter of time before you will figure those animals out. FYI, I hunted for 7 days this last year with out seeing an elk, in a unit that I have hunted ever since I was a kid and have had a 80% success rate with my archery tags. It was on day 8 I found the elk and killed my biggest typical bull yet.
As Coloradoboy said it right when you have to consider what others are doing. It is amazing what heppend when you find areas where others are not hitting. Be it a 3 mile hump in or that special spot 1/2 miles off the road. The elk know people, they know our habits and will adjust. I have found tons of elk short distances from the road, just in spot that people over look, hike past, etc. Keep working your unit and things will work out.
Do you call at all? If so what is you calling sequence like?
