Don't have a passion and don't want one at all. I'd feel short changed to get hung up on one animal.
Just different strokes for different folks. I love learning about new animals all the time.
One thing, other than a Kudu and Cape both with bow, that I have absolutely no desire for is Africa. Before I'd do that I'd have to take everything we have to offer here in the good ol USA before I'd even think about spending time and money in another country hunting. Dunno why. Wouldn't mind visiting though. But not enough spare time for that.
