Not very far in, but I find this hilarious
When we get close to the river we find a police post and a settlement. We have been told many stories of corrupt police. That you have to report to the police in every town. That they ask for copies of all passports and other papers. People even take documents with with lists of the travellers and their passport no’s, explaining the purpose of their trip in portuguese etc.
As we stop in front of the police post, Hennie’s approach is to make the universal down-the-hatch sign and shout “CERVEJA” at the approaching policeman. Less than a minute later and we are downing beers under a tree with the police.
Try that one next time you see the Buffalo PD.
