I Green Hunted a Rhino in 2010. My personal experience was great.
I started by doing serious research on the right PH, and together we worked through locations and hunting options. We found the right opportunity on an animal that had not been darted and required conservation data (turns out she was pregnant after all). I spent the better part of a day getting into about 18 yards, the problem being a independent young Rhino she was hanging with was incredibly alert and anxious - I was really surprised.
I completed the stalk to 18 yards in bare feet with my PH hanging back at about 50 yards and the Vet and my wife about 100 yards back, running video. The video of a very alert younger Rhino standing guard while the older Rhino can for a while be seen resting/sleeping, and heard farting so loudly it was picked up on the audio 100 yards away, is both awesome and hilarious.
The hunt went very well, was harder than I ever expected, and the photos of working with a live Rhino continue to be the most talked about in my trophy room. My taxidermist did a fabulous job of recreating the "horns" based on the detailed measurements and photos. The reproduction "horns" hang proudly in my trophy room and, to me, are every bit the trophy as the real thing.
I have no objection to the traditional hunts, for the reasons discussed above already; it just wasn't what I wanted or could afford to do. I fully support Corey Knowleton's Black Rhino conservation hunt in Namibia and would be the first in line for that experience if I could afford the hunt.
Like many things in hunting, I don’t think there is no "right" answer to the question asked. Hunting has become a complex issue of sustenance, sustainability, conversation, sport, heritage, family bonding, and so on. So long as we leave the hunting species better than we found them, let the debates on methodology role on unresolved. It's good fodder in the off season.
