The best and most popular form of transportation in Mwanza outside of your two feet and a piki piki (motorcycle) is a Dalla Dalla. It is exactly the same as a ZR in Barbados. The same van, the same way they pack people in like sardines, the same paint jobs and music blasting, everything. And you'd think that there's a school of madness driving that Bajans and Tanzanians go to get their licenses. (Trinis, Jamaicans, other West Indians and Africans, please comment on similar ZR/Dalla Dalla type vehicles you've encountered.)
Oh, and in Mwanza city centre, there's only one stop light. And to be honest with you, I feel safer making a mad dash across the street than waiting for the cross walk.
