Hello. At the end of this year me and a mate are doing a charity ride from London to Cape Town. We have most of our S### sorted like carnet, insurance, shipping etc. My question is about insurance card in Africa - e.g. Brown card, yellow card, pink card. I assume these are able to be purchased once I enter each specific zone. Am I wrong? is there a way to buy these insurance cards in advance? Also have heard a vicious rumor that if you travel from north to south you will not be able to get a visa for Angola. This sounds strange and have not seen any evidence to back it up. Anyone else heard of this?
