it is not easy to see the big five and hunt plains game at the same place, especially in SA......spend a few days in a park like Kruger. Shake off the jet lag and see the big 5 plus a whole lot more....then go on your plains game hunt....there are several threads about this with several suggestions of good operations to hunt with...not sure what free ranging means to you....in SA some operations have thousands of acres fenced....if fences bother you, you might consider Namibia or Zimbabwe....
