Seven hours in a car

Today I went to a comunity called Gabela and also to a place called Sumbe to see the Waterfalls' Park. It is hard to understand, as a human being, how can it be possible that water is such a rare article here when you have rivers and a waterfall like this, even though I can understand it as a biologist.
In the Park, a man was charging for the entrance and holding a book we had to sign before entering, with our names and birth country. He didn't work for the government or for anyone else, but was alone doing that and getting money from the tourists. Smart guy. He also has to find a way of surviving.

The kids, on the back? Fishing.
The kids, with the hoe? No idea.
