The current 'black spots' you all know about, so forget going there!
I travelled the world, by myself, from when I was 18-23. I never had a problem anywhere, but was very cautious, & was guided by 'horse sense'.
It was just a big adventure to me to see the sights, listen to the people speak, & eat that country's particular food.
I was very fortunate to do what I did then, &, of course, the world was a much safer place in the '70's!
