On the routes where the roads are bad, or the population cannot afford even Bolivian bus fares, a camíon or truck carries passengers. This is an open truck fitted with wooden transverse planks usually at varying hieghts in order to maximise the number of passengers. Luggage is dumped on the floor and firmly trampled down by the human cargo. There's a tarpaulin if it rains. The camíons go to the most interesting places, however the plank is hard, I find three or four hours enough! It's best to get a seat at the front as there is a better view and something to hang on to! The camíon also carrys frieght, usually passengers sit on top of that as well. Tyres are usually bald and punctures frequent. The normal standard of lunatic driving prevails. However I noticed that at the ferries even Bolivians got down off the camíon leaving the driver to take his chances down the steep river bank and embarking only when the truck was esconced on the ferry!
