Dear Chris, that’s not a stupid question by any means. I have spent the last five years thinking about logistics. The short reply is: I source absolutely everything from the States. There is zero possibility to attain equipment locally, and in the off chance I could, whomever controls it behaves as if they possess the kit’s own weight in platinum. It is very difficult to bring anything into Patagonia without having to deal with cost-prohibitive taxes, penalties, etc. The best bet is to simply ingress as a tourist, which unfortunately means removing all the equipment from the country after a period of 3 months, although it is not uncommon to make a token trip out and return the same week in order to be granted another 3 month stay.
Ps. Also, one learns what works and what doesn’t. For instance at first I took an Apeks ‘flight’ regulator, a beautiful low profile unit. Later I realized that a proper cold water regulator is needed as free flow would occur every once and a while.
Ps2. Fishing? Are any of you guys familiar with Riffe
