Travel can be an adventure, at times I have gone out of my way, to stay out of the way of trouble. I have encountered street protests, in Paris, Rome and Athens. General or transit strikes in Athens and Rome (the one in Rome was for four hours.) I have worked my way around political protests in London, Chicago and of course Washington DC. There were riots in London one trip.
I go around, stay away, don't take sides, don't voice my opinion. It is fairly easy to do.
There are places I have not traveled to because I am uncomfortable with security (Egypt for example.)
