oh yeah, and if you go on the safari, bring school supplies, stickers, pencils, crayons, toothpaste, tooth brushes, maxi pads, small things you can easily carry in your suitcase from home, and they'll make a stop off at one of the local schools where you can donate these items. I got all my stuff from the dollar store here.
DO NOT throw money or change at the kids chasing your bus or truck. You're not doing them any good, they're trying to encourage the parents to send their children to schools and get an education instead of begging, and trying to discourage any form of it.
