Mine was a white.
A couple other thoughts, and I believe all have been talked about on other threads so you can search for more info.
Consider either a dehorned rhino or look for a deal where you don't tale ownership of the horn. The horn is very cool to own, but also one big PIA. At least I keep it locked away and there is that expense ongoing and what do you do with it long term? A couple years back there was a deal where it was $6000 cheaper to leave the horn behind. Yea it is theoretically worth a whole lot more than that... but illegal to sell. Doing it over and given the opportunity, I'd save the 6k.
I did a full mount. Do NOT place that behind the couch in the living room if there is a woman in your life. She may think it's cool to start with, but even the most understanding and active hunting wife will eventually come to dispise the rhino in her living room
You must apply for the permits to hunt a rhino in RSA well in advance and must have dangerous game hunting experience as well as be a member of a hunting organization such as DSC or SCI.
My hunt was in the correct place and correct Province to have the best honest experience. Contact Bossie for more details as I won't publicly post. I had to shoot targets in front of the Provincial Game Manager in attendance. He was good at staying back out of the way but was there to be sure the hunt was conducted properly.
Be prepared to shoot accurately and follow up without the PH backing you up. Unless human life is in immediate danger. At least on my hunt in that Province, there was to be no backup for a bad shot other than by the hunter. The official instructions were of you don't kill it, you will follow it up no matter how long it takes. I loved that! He didn't move 5 yards but the risk is on the hunter.
Last I heard, wild Black Rhino hunts in the Namibia parks were very limited on availability, takes a bit to get a permit to import to the US and you'd want that before the hunt. And cost had dropped to about $150,000. Not sure if that is current info.
There are some Black Rhino dart hunts available, in RSA. Expect about 1.5x to 2x cost of white rhino dart.
Come to the AH dinner to discuss rhino dart hunts with Outfitters
When you go do the hunt. Keep your mouth shut! Everyone involved needs the hunt to be secure and so does the taxidermist. Don't even use your phone within many miles of the location.
