I'd agree they need thinning out dramatically but believe it should be done in a scientific manner....... the books will really give you an insight into Elephant relationships and dynamics and although I'm sure you won't agree with everything you read (any more than I do), by the time you're finished you'll have a very different opinion on the subject than you do now......... There's nothing more interesting than Elephants......... whether you're hunting them or just studying them.
