Two places to consider that I hadn't before:
1) Bosnia Herzegovina and 2) Moldova.
Why these two?
Update on Russia.
I was in Moscow, mentioned earlier in the thread. Very low on masks indoors.
I got on the train to an obscure sub-500K city. The woman verifying passports for the train was unmasked. I was moved into three different sleeping cabins as people wanted to move themselves in with their wife/girlfriend. None were wearing masks. Shared a cabin with a guy who would have his bank accounts closed for having the wrong ideas if he lived in The US, unmasked though he was vaxxed. None of the reception or restaurant staff in my hotel are wearing a mask. Everything is open. Churches are maskless. Shops are maskless. Only seen masks worn by two supermarket clerks.
This is apparently correct -
I doubt they will open up too much to travel and entry is limited to certain passport and residency visa holders. UAE visas, which are easily obtained, can enter with a negative test. I imagine you could also enter with a visa to learn Russian in a university.
