Manaus, Brazil
The main economy of Manaus was once Rubber. Today, it is Robber -as in Highway. I finally feel like the tourist with a great big M on his forehead.
It started at the airport when some guy spotted the great big M on my forehead and swooped in for the kill. His skills were off somewhat as he mistook me for German and began speaking German to me. Once he realized his mistake he then switched to English. He could arrange any thing I wanted: a boat cruise, a seaplane...
