...Are you hunting private land or the last great unknown drainage? There is no such thing as a non over-crowded spot now unless you are on private. Anyone can go on OnX or Google Earth and find trails, parking areas, etc. You're not even really hunting some of these spots any more than you're just hoping the group 300 yards away on the other side of the drainage bumps the herd over. You found the last known honey hole in the state.
If it puts anything into perspective, my house backs against BLM Land, followed by FS and wilderness. I rarely see more than a handful of cars in this area in peak Summer season on a Saturday (Massive FS/BLM Road system). Come September, its a zoo. I can't even find parking along my usual pull offs so I ride my four wheeler up to my spots. People are tent camped right at the trailhead parking lot so they block access. People in 20+ man camps tearing up the spots. SidexSides flying 50 mph down the twisty dirt FS road with blind corners. Trash everywhere. I can't even imagine the hell the trailheads near Vail/Silverthorne see.
The license plates? 75% NR. I used to welcome other hunters, but the pressure in the OTC units and general lack of ethics has caused me to have a strong distaste in my mouth from out of staters and res as well. Handing out OTC tags to any swinging body needs to stop. Too bad the cash cow won't let it.
