When I was a child I loved USA, thought it was great country, and dreamed of visiting it one day. Now, when I'm grown up and finally I can afford intercontinental travel I am seriously afraid to even enter USA. I might be arrested for no reason, or have my cash forfeitured, also for no reason... I think that few remaining free countries in the world are Switzerland, Singapore, Australia, and maybe Hong Kong
