I would love to know myslef but unfortunetly people don't like giving people the locatins of "good spots" esspecially over the internet. Unfortunately they have good reason not to, if pochers or "collectors" saw these locations then it would ruine them. On the other hand, its like with fishing, you don't want every Tom, Dick and Harry crouding your spot haha. If you want to know good spots, the only real way to do it is to go out and find it yourself (I mean unless you family or freinds who know a spot or two) haha you just need to keep in mind which areas have everything needed to spport a varety of life (food, shelter and water). That doesn't just go for SA either, its the case pretty much everywhere.
Good luck
