Africa? Seriously? First thing niggers are going to do when they see you've made wealth is GIBS ME DAT WHITEY. I mean shit, it happened in that very region quite recently.
You need a ship or an island. See this bad boy? It can be repurposed with enough dirt to make a farm and onboard lake, as well as living quarters for all y'all faggots. You can make spare cash transporting shit too, and have access to world markets sick ass guns & hoes there's a reason pirates saw the sea as freedom. Eventually buy or claim an island, that would b cool.
Most viable thing though is just to buy some parcels of land and set up a ranch, with others involved or just see if anyone comes. 'Merica is a good place to do it seeing as we have good gun laws in most states. Nobody cares what you do while fucking off in the woods as long as you don't break the law too much. Best states to do this would be Alaska, Northern Arizona, Utah, Montana… There's plenty of other viable options.
That's just my 2.00 cents.
