[Nation] When I arrive at the Seronera Airstrip in Tanzania's central Serengeti National Park, a slim woman in her mid-20s dressed in a crisp safari guide uniform is holding up a sign with my name on it. I have been on close to 50 safaris in my time, and Lailatu Wilfred Kivuyo is the first female safari guide I've ever encountered. She is one of only three female guides in the Serengeti.
