Turkey - I have killed them, called them in, etc....it's fine but in the Spring I would rather be fishing.
Bears - never done it....seen a bunch of grizzlies in NWT, was definitely puckering, and would shoot one if I needed to in a heartbeat.
Zebra
Giraffe
Deer getting run by dogs - I did deer dog hunting once in N Fl. 3 generations of family hauling ass on dirt roads talking on CBs....eating pigs feet, vienna sausages, some folks drinking beer. Slam on brakes, get out, barking gets closer, deer runs out, all hell breaks loose. People shooting and hollering. It was fun but seemed dangerous and indiscriminate.
Hogs getting run by dogs - Tried this too.....hog screaming bloody murder while the hero picks out his weapon. Saw a guy use a box cutter like he was a real badass. I felt bad for the pig sitting there squealing and how he had to get killed like this, and by that guy, in that manner. Was not hunting to me.
A treed cat, or anything else cornered and afraid.
Being from GA, my first big game hunting was deer out of a stand. It's a way of life. After going on a sheep hunt, training and preparing for 2 years prior including exercise, diet, reloading, shooting at distance, and hauling 85# for 12 miles on the packout through grizzly territory, I obviously don't look at sitting in a treestand back east and waiting for a deer to walk by the same way anymore. But I also don't look down on it. It is a part of who I am, and a part of the culture of where I am from. Alot of my buddies who have only whitetail hunted back east, never been west of the mississippi or north of the border, and heard about my sheep hunt think I'm just a guy who wrote a check and pulled the trigger. Lots of folks on here probably do too. It changed my life and changed me in the years leading up to it, and certainly during and after. Writing the check and pulling the trigger were the easy part. It's everything else that I remember and that changed me.
Interesting reading all the replies. Obviously we are all shaped by our experiences (or lack thereof) to date in life. Some of it seems like sour grapes/insecurity. As an example, I live in Florida and I can go out right now and get in my kayak and go catch a 30 inch snook. I live here and know what to do, where to go, what tackle to use, where to fish, and why. But if a guy from Canada wants to come here and go on vacation and use a guide to catch a snook, I am happy for him that he gets to experience that. No, he doesn't know what I know, but how could he? And why does that matter? I don't understand why people have to constantly put themselves on a pedestal. I swear alot of people out there are just miserable and are insecure.
