I'll try to make this complaint as short as possible. After a day of walking around public land for pronghorn I decided to pull out and glass into the area to plan for the next morning. Something caught my eye while driving and I turned around, pulled off onto a dirt road and glassed. Boom, found my perfect Colorado public land pronghorn buck. Unfortunately, there was roughly 30 minutes left in the hunting day and the buck cannot be accessed legally from the road but from the parking lot 3 plus miles up the road. Since I definitely can't get to him before the time is up I saved his location in my onXmaps and planned to starting hiking to him at 5am. Sadly, my actions of turning around and glassing caught the eye of a couple old, fat, and probably drunk hunters I had run into earlier in the day. As I drove away I noticed that they pulled out of their spot and headed to the dirt road I glassed from. I drove home thinking no way they would illegally hunt from the road right? The next morning I'm the 2nd person in the parking lot and I see the first hunter hiking away in the opposite direction so yesterday evening's buck is all mine! I set out and get to his spot and all I find is evidence of a kill and carcass dragged away to the fence line/road (150-200 yards). I can't guarantee it was the folks that saw me glassing but all evidence leads to it. I saw most of the same hunters the next day excepts those fellas so either they had other things to do or they filled their tag the evening they saw me glass that buck. This hunt hurt a lot knowing I had shoulder surgery so every ounce on my back sends a pain through my nerves down my arm and bad knees from jumping out of aircraft yet I will hike nearly 12 miles (attachment to back my claim) for a legal harvest but those old fat folks take no shame in hunting from the road. I am done with eastern Colorado pronghorn hunting, put me on the CO NW BLM waitlist and I'll go to Wyoming until then.
