RE: Another ethical question...
First of all I ain't a penned hunt guy either but it does sound fairly large, so not as bad as some might be but hardly what we would call hunting. Being it is basically free and been asked to help cull the lessers...I would go and do it. If nothing else it will provide you with experience in the field, shot placements and heck a nice set of rattlin horns to boot. Now if you have a problem with it personally or no real desire, then don't go. If your problem is with what others may say or think......who cares!! You are the one that has to look in the mirror, do what makes you happy and feel good.
