teach a kid or a adult that has never hunted the basic hunting skills,tell him what is legal to kill and let them decide what size animal they want to shoot. i find about 75% will choose to only take nice bucks and let the small ones walk after they hunt a few years. but if they don't ,thats fine . let them be meat hunters. to start with they need to learn on there own that they can go out and kill a animal ,gut it ,skin it ,cut and wrap, and eat it. i think teaching the whole proccess is important.
i know plenty of guys that have hunted for 20yrs or more that could care less about horns.
