Re: Timely advice
My grandfather had friends in West Berlin - they were almost free to visit their relatives in the East.... but not vice versa (they wouldn't have returned, of course...)
Some Eastern countries "welcomed" some tourists especially when they brought in some precious foreign currency, unless, of course, they had reason to deny entry because someone could create "issues". There were often limitations about where you could stay and where you could go.
Anyway I was planning to go to US this August to watch the solar eclipse, but I guess I'll go to some other more relaxing place and spend my money there instead.
I'm also afraid Trump & C. could think the eclipse is a sign of ire from god - or some Muslim terrorists hacked the Sun, and you really don't know what they could do...
