We’d just arrived in San Martin the day before, fresh off a good night’s sleep after enduring a marathon series of flights pushed together tightly to avoid a planned airline strike in Argentina (while the strike was a major pain, we were both grateful that airline unions had the courtesy to let us know ahead of time). We had a day to kill before the rest of the crew showed up to chase trout with our hosts from Patagonia River Guides, and we were up for anything.
