Baz Buz, South Africa

While in South Africa, just about every backpacker that I met along the way was traveling by Baz Bus. All you need is a one way ticket to some specific destination (say you're going from Cape Town to Johannesburg). With that ticket you can take the bus and hope on and off wherever you want along that route. I haven't found any other form of transportation anywhere as perfect for backpackers and independent travelers like Baz Bus. You'll meet plenty of friends along the way and have the trip of a lifetime.
