Region 1, 2, and 3 bordering close to WA as well. Personal struggles tend to inflate the issue. I believe the NR plates simply stand out thus take a larger brunt of the heat. I recall pulling to a tiny corner of public land that's always been an unknown across from former block management now cornered with a large swath of "corner crossing" to public.
Finally made it to that little slip we've considered "ours" to find, for the first time in 15 years, four WA plated trucks, two campers, atvs, horse trailer, pecker poles nailed/roped into/onto trees for hitching, my meat pole I Dsnow9'd my way up to create our first year there, already hanging elk bags... on and on, we sat in the truck, very bummed and bent at the vast blown up camp setting typically used by ourselves and one other camp set by 3 MT plated couple good guys, Two-three trucks max, two wall tents and utv.
It's perfectly legit for them to hunt out of and camp there though it was a kick in the nuts, regardless. Had this been some other MT plated group - we'd still feel like chit though the vent point was the NR plates.
What I'm getting at, WA / NR plates really stand out to me when I'm sour about showing up only to find another truck(s) at the location. I hunt less populated deer/elk areas to stay away from hunters. Reality though, it's $$$ for FWP operations. I'd like to see less NR plates though that's a bean counter operation for game population density vs NR $.
After all, for some lame reason we have the oxymoronic belief to gripe about NR's yet be damned if we pay another nickel for our Resident tags!
Just a ramble.
