Where is Flipper?

After we saw the confluence, we went up the Rio Negro towards our jungle lodge. We were told by Oswaldo that we might be able to see some of the dolphins that live in the Amazonian rivers. Both gray and pink river dolphins are present in the river, alas we didn´t see either on our trip up river. The only pink think that happened was the sun burn I got on my face while we were hanging out at the bow of the boat and than under the "shade" on the main deck. The weather was alternately sunny and over cast and spending five hours on water without sun screen (the one day I forgot to put some on) was enough to make my face glowing. Three days later I still look like a lobster.
