Most of the time, if using a respectable taxidermist in Africa, they take care of getting the trophys back to your home state. So there shouldnt be any worries there. I know a good taxidermist in South Africa if you need help with that. We run trips in North East South Africa for all of the species you mentioned so I'm very familiar with your trip if you need any more advice. Just PM me or give me a call and I'd be glad to help or answer any questions.
