Never watched it, but when I was a prostitute, err a consultant, I went down to Brazil to visit Embraer Aircraft & do some work. One of my clients use to work for an airline that ran Beech 1900 up & down the Amazon and asked if I wanted to go for a run one weekend & fish.
I said sure and we had quite the time fishing for some mean a$$'d catfish type fish & peacocks. We'd land at some
strip that called itself an airport, get some guy to take us out in a small skiff, and catch some unreal fish.
Never knew what the cargo the plane was carrying, and since I was a guest, never asked.
We were also told to watch out where we pee'd because there was some sort of micro bug that traveled up your stream & laid eggs. Convinced me not to drink much before we went out.
