In most of the places I visit in Idaho, people at the very least are pretty much not wearing masks outside, and other than "mandatory" places like Costco, a lot fewer people are wearing them inside. There are plenty of places that still have the "mandatory" sign on the front door, but they (unlike Costco) are not enforcing it.
Unmasked people in those places are not attacked by Karens, and masked people are also left alone to wear their mask if that's what they want. I seem to see the same philosophy in Easter Oregon, though as KGB mentioned, there are still state mandates there so I see more people in masks. No real enforcement though.
This week I am in CA, and it was almost a shock to see everyone outside everywhere with masks. I have not been following that, but am way in the minority. I also see a lot of people driving alone in their cars with a mask on. I'm already irritated in having to constantly walk back to my car to get a mask because I was going into a place where no one cares in ID, but you get accosted here.
Just three hours ago, I was helping my 93 year old aunt walk into the restaurant where we were having a get together group lunch in a private room, and the hostess told me I had to go back out and get a mask. As I was holding my aunt up at the time, I ignored her and continued walking the 20 stinking feet into our reserved room, where she said we didn't need a mask.
The Best Westerns in Nevada have been sticklers for masks at the registration desk, and said you need them everywhere outside of your room, but other than the front desk, I was blowing that off and no one has said anything.
Anyway, it has been weird seeing the variance, especially between ID and CA.
