I grew up in Colorado and share your frustration. Hunting was easy growing up. We could hunt elk close to home and there were elk to hunt. Co dept of wildlife culled our herd so heavily that going home to hunt is just walking or riding trails vacationing now. The heavily pressured herd has moved off national forest through blm to the canyons between farm ground. Access is tough as private blocks the blm below. Yes it is just changing times but living through it wasn’t fun trip.
To be fair, the elk finding the alfalfa in the 1980’s and resulting crop damage payments drove the culling but they way overdid it in my opinion.
there are good hunting areas still but finding them on the internet will be tough. The center part of the Colorado still holds a lot of elk as does nw Colorado. Hold lots of hunters too.
