i wish i could find this company/guy/video i remember seeing.
something called "adrenaline hunting" or something.. they had a promo video showing the british owner/guide yelling "wait wait wait" while rhinos/etc are charging at him/hunter and then "shoot" or "now" when the thing is like 6-12 feet away, and the hunter downs it with an elephant gun or similar high powered rifle.
i can appreciate why some people would be interested in that, but not for me

although im not a huge fan of sport hunting anyway, that kind of thing seems to be the way to do it IMHO if youre going to. makes it a little more interesting/"sporting" shall we say. (ive never seen the point in hunting deer with sniper rifles or compound bows with night vision scopes etc)
