Visiting the Matses

Someone wrote on FB that they are in Iquitos and want to visit the indigenous Matses. I wrote this, then decided not to put it up, because while meant to deter people, it will probably only encourage them. But since you guys ain't going anywhere, I don't see the harm in posting it here.
Natasha: First, you need to get in touch with the military and see when their next plane is going to Angamos. Get on it. Get to Angamos, a military base, and there is a Matses camp nearby. Don't forget to get chacira, a couple of kilos. Those are Chezhoslovakian seed beads, made from glass. They love those. Rarely sold in Iquitos. Then, unless you want to stay in the dire community near Angamos, you'll need someone to rent you a peque-peque and someone else to sell you gasoline, which they don't always have there. When Angamos is dry, the few people who have some gas might charge you $30 a gallon, and you might need at least 50 gallons. Be prepared. Them the boat owner will take you up the river to a village of very westernized Matses. They will likely charge you to visit. Just a hundred or two for a day or so. You will probably need to bring your own food: They might have a little for you, they might not. Do not expect that by paying a hundred or two hundred and giving each member of the village some seed beads that you will be invited to stay overnight. Mostly they just want your gifts and then want you gone. I could go on. At least they won't shoot arrows at you as you approach anymore. But these are not tourist injuns. These are people who generally do not want outsiders in their camps. That becomes more true the further up either the Yakirana or Galvez you go. Some people have been lucky and made friends with village headmen, but not many. Outsiders are a drain on their communities for the most part, which is why they're not very welcome, or welcome for only a day or two at a camp, essentially while your presents for them last. And they will want presents every day or twice a day, so be sparing with those seed beads. Ruber Castillo and Jhonny Java can get you in for a few days but will cost you. Ask for them at El Noche restaurant on the boulevard. But this is expensive, no fooling, and is still only for a few days, tops.
