The first few photos here are of the motocross racetrack. As you can see, it's perfectly safe and well kept up. There are races most every weekend.
The rest of the photos are on the same road, in the better part of town known as Talatona and also Nova Vida. The Xyami shopping center is fairly big and has a the only Pizza Hut in Luanda, along with a KFC. It also has a very nice home goods store - the one I bought my cow fur chair in.
