They're just like every other group of people--some good, some bad, some smart, some not so much. I've never had even a warning, but enough interactions nonetheless to form an opinion.
In Nevada, a family friend is a retired G&F LEO. Couldn't be a better guy in every respect. Good, smart, caring, committed dude I would want by my side in the worst of situations, even in his old age.
In Indiana, I came back from a midday duck hunt in an area known for meth addict hill jacks, and two wardens stood up out of the brush ten yards from me as I approached my truck. Lucky no one got shot. From the conversation that ensued, good people, not so bright.
In Wyoming, I had five interactions in three years with a warden in Area 7. Jerk and a fool, unequivocally so, doing nothing but shame to public service.
In Idaho, endless friendliness and I can't pay them to look at the licenses I bought with my hard earned money. Kind of wish they'd up their game a notch or two, because I see enough dirtbaggery to warrant attention.
