In answer to the question...
Our road is widely known as the worst in town because the soil is a very sticky clay. It rolls onto the tires like this, so you're just sliding around clay-to-clay, with no rubber meeting the road.
One morning after that happened, I thought maybe I could knock the mud off by driving back and forth real fast in the graveled parking area in front of my house. It didn't work like I expected, but I wonder if this is the same as studded snow tires?
Just to add insult to injury, the morning after sliding through the mud, we ran out of water again. So we hauled out the jerry cans and fetched some. After that much rain, shouldn't the city of Arusha have enough water to pipe some out to us? That pile of tires is there waiting to be sold, because I bought new tires, hoping for better traction. Does this picture make me look like white trash? Or mzungu koko? Koko being the Swahili word for describing a stray dog, or a white person who's run out of money and is stranded in Africa and is not looking too well cared for.
