Dude, I've been hunting dozens of times with my dad when I was little. I've helped him track and butcher dozens of deer. I know my shit when it comes to these things. I just wasn't strong enough to draw a 40 lb bow until after we couldn't hunt there anymore. Some ass from Lousiana paid the farmer $10k a season to lease the hunting ground. Then they charge a bunch of people from NY or something to come down and just wound deer left and right. Pisses me off.
When you bowhunt, you are doing it more for the challenge than just to kill a deer. If you just want to kill something, use a rifle. Bowhunters rarely miss because you practice for countless hours, time your shots, and know your limits. Most shots are taken from less than 30 feet. Even if you do just wound the deer, it has a much better chance of survival later than if it got hit with a bullet. They cause so much trauma going in that a wounded deer won't live more than a few days. If you hit a deer with an arrow, there's only 3 possibilities: 1. You hit the heart or lungs and it dies pretty quick. 2. You get a gut shot and it dies a slow, painful death over the next 12 hours (still better than being hit by a car in many cases though) or 3. If you didn't get a gut shot or hit the vitals, the deer will pull the arrow out in some brush or by rubbing against a tree and will most likely make a full recovery. I rarely ever see people get gutshots because they are a bowhunter's greatest fear. If you do that, the deer will be healthy enough to walk around for several hours but it won't bleed very much. Then you get to follow a nearly impossible blood trail for the better part of a day until you find it.
Even if you don't like hunting, somebody has to do it. There's way more deer today than there were when Europeans first arrived, and we've killed all their natural predators since. If left alone, their populations skyrocket and they die en masse of disease or starvation. Deer/car collisions also greatly increase, and quite a few people die as a result. Maybe it's just me, but it seems like a quick death is better than long, drawn out suffering.
I'll stop now before this gets moved to the OT forums or something.
