I want to go on a 1-2 night safari in late July 2013. I've been looking at some packages, and they seem too rich for my blood. I do not need running water, a bed, fresh food, or a tent. I'd like to rough it as much as possible. However, nearly all the tours I see include some costly western comforts that I have no need for. What's the best way for me, and a couple of friends, to go on safari with as little guidance and cost as possible? I'd be leaving from Nairobi. I do not mind heat, bugs, getting dirty, or getting into hazardous situations. Thanks.
