My father just got back from a two week trip in Brazil. He spent the first week doing missions work in Manuas and then he spent the last week with my family in Rondonia. He took a picture of these two rivers that run side by side of each other. I know it doesn't sound interesting, however, one river is brownish and the other black, and yet they don't mix. I've heard about this river from my family but have never had the chance to see it up close. Check it out...its pretty cool!
