My visit to Brazil some 30-35 years ago, I stayed with a native Amazonian Indian family who had never seen a white man before, they were not cannibals despite the old mansharpening his knives each day, thank god i had 200 John Player Specials, he enjoyed eating them !! & later I showed him how to smoke them.
His wife thought I was ill being of pale complexion, the water was roughfrom the Rio negro, not too good on the stomach
The family decided to take me out in the canoe at night to meet the crocs 3 & half metres in size.
A croc they caught & tied it up with a log in its mouth, they did not kill or eat it, rather scary in pitch dark the decided to restle with it whilst i was bailing out the water from the canoe in the pitch dark, when they caught it they put it in the canoe & we had to sit on it rather worrying! A long uneasy journey back to the hut & hammock.
In the morning they cut the ropes holding the log in its mouth, typical brit I was standing there taking pictures, he moved rather fast, whilst i jumped up to the house on stilts I have never moved so fast !! my poor old zenith camera survived tho.
