Dakarou, Capital du pays des gaindés. To change money always go to a bank. Avoid the black exchange market. There's always a lot to do especially when you've been able to get acquainted with locals. The Dakarois tend to see you as a walking money-bag, watch out and don't trust to quickly. First get the gear, than pay for it. Taxi-transport is an attack to your personal safety (before you leave, check if lights, doors, etc are working / closing properly, if windshield is intact) Negotiate price before you leave (try to divide the asked price by 4). Do not drink tab water or take a drink with ice cubes (You'll get very sick, trust me). Beaches of Sally are the best I have visited so far.
