I’ve gone to WY twice, both times were pre ONX, and trying to make sure we were on public land on the first was a PIA. Ranchers would follow us around hoping you shot one on their ranch, as GF would hit you with a fine you had to pay to them… the next trip we paid a modest trespass fee to a local rancher who limited hunter numbers for lots of land , and it was waaay less stressful. Worth the money at the time, albeit that was 20+ years ago
