I would be hard pressed to pick one animal, but I do love to hunt Kudu, and Eland are huge and that adds something so I better include them. Gemsbok are so majestic that one could not leave them out. Those are the top three requests I get when booking plainsgame hunts btw...
I love to hunt the Mountain Rhebok, and the Vaal Rhebok, that is a test of your skill with a rifle if there ever was one and The Bushbuck has to have a special place with me. I never come home without another Zebra, come to think of it, and I especially like the Zebra of Tanzania.
A big old wart hog is something to behold, and never overlook the beautiful Waterbuck or the Nyala and who would go to Africa and not shoot the Wildebeests, Impala, Springbuck..
If you include the USA, you have the Whitetail, Coues, Del Carmen Whitetail, the huge Whitetail of Canada, Mule Deer and Pronghorn and the Rocky Moutain elk, bighorns and goats..tough choice, couldn't make that one.
It is almost impossible for me to pick a favorite, but if push comes to shove on one animal that I would pick over all the rest and if you include the big 5, then I would pick the Cape Buffalo. I love hunting those black bulls, always have and always will...
