Its tough just when you think you got it dialed in you don't. My elk stand is 1 mile off the road, usually I may see one or two guys, Last year on the opener I had 18 people walk by me and a couple of the small groups sat on the same log at different times throughout the day and decided to have a BS session. Then on my deer hunt 1.5 miles off the road I sat for 50 hours over 5 days and only had one hunter walk by.
