@Ruby: Everyone hates Americans, deal with it
No seriously they are said to hate Brits and Germans, too and I'm not convinced that they are such hateful persons.
And I think Paris is full of tourists, you shouldn't have so much problems there. If you go somewhere to the countryside it may be different, I don't know.
We were at ... Place de la concorde I believe and crossing the street was just scaring. You never knew when the cars would come because they didn't seem to pay attention to the traffic lights at all.
