They are never, ever fenced in. And the fencing in is a very dangerous thing because migrating animals can no longer migrate. For example, we visited the Karoo National Park in South Africa and wanted to see the black wildebeest that occurred there. And when we arrived, there was none left. And we were told yes, during some seasons they stayed here but then they migrated because there was not enough food during other seasons and the migration was impossible through the fence. So I think fencing in is a very questionable procedure. And Tanzania is very happy without fences.
