Saudi Arabia - I'm used to traveling on my own and they require women to be accompanied by a man at all times...no thanks.
I would not like to vizit Iran,USA.I do not know why?my intuation says me do not go:).
Maybe USA, because I love to meet new cultures and USA,at least for me, seems a "Brazil that speaks English". This is my opinion.
Nothing against american citizen.
USA I don't like because I hate this imperialist country.
