Crossing into the Tropic of Capricorn in Botswana

After checking the internet today for the first time since Lusaka, We left Francistown for the capital of Botswana, Gabarone. During the drive we passed a rusty sign that read "Tropic of Capricorn."We had crossed from the Tropic of Cancer into the southern Tropic of Capricorn. Never thought that I'd do that, or even desired to. But it was cool to imagine crossing that line I'd seen across the globe.
