I just took the Utah Hunter Ed course, and a large portion of it had to do with ethics.
Congratulations!! Very excited for you and the hunting community. That is great. I happen to be a Hunters Ed instructor also, and I agree ethics and conservation are vitally critical. Every instructor is a little different in how they address this issue.
I personally emphasize not to be disrespectful of the animal, but if you want to carry it so it can be seen do so. I also emphasize to be proud and be educated on the second longest standing heritage action of America. (First is arguing with authority..LOL) I think not showing others I hunt and the benefits of it eliminates others who may be interested. I know for a fact I have been able to have others become interested in hunting because of seeing that I hunt and the successes of those hunts.
Now to throw a wrench at this...I never have any animal exposed while transporting near any place where I hunt. Why? I don't want anyone to know I killed something in that area. We don't even hang our animal quarters in view when at camp. Nope...we never kill anything...nope never....this is just about getting away from the wives. Good luck and hopefully we see some pics of your hunting.
