Black Lightning, hope I'm not butting in here, but I guess you have a fair question and each of us has a different take on these things.
Your question about taking a Giraffe is about the same question I get from some people about shooting a Zebra. "After all," they reason, "isn't it just a pony?".
The only way to answer is to go over there for yourself and expose yourself to this hunting. When I got back, one of the first questions my wife asked after seeing my pictures was, why didn't I take a giraffe?
Many more hunters would take giraffes except for a couple of things- the trophy fee is fairly high compared to other plains game, and the taxidermy and a place to display such a unique trophy is kind of difficult to deal with, logistically.
As a trophy, when you see a giant Male giraffe in the wild, they are one of the most magnificent creatures I saw the whole time I was over there. Just like other game, they need to be managed also to keep their numbers in line with their unique habitat needs. Taking one with a bow is an especially interesting way to take one, as they can be difficult to hunt.
Sometimes we would see them from the truck a mile or more away, then when we approached where they were standing just a moment ago, they were nowhere to be found and couldn't be seen anywhere. For something that large to hide so completely has to be seen to be believed.
Don't know if this answers your question completely, but your asking it brought up some great memories of seeing those incredible animals running through the bush, their colors flashing in the sun.- Sheister
