Well said L_K.
Too, some may not know but there are anti-hunting organizations out there that the main topic they use to promote their anti-hunting agenda is hunting related shootings/accidents. These groups are not hard to find with a quick 'Google'...
...soooo, since I love to hunt, and wearing orange whether required or not is a proven method of helping preserve what I love to do by cutting down on hunting related shootings , it seems a small thing to do.
FWIW, putting hunter orange on a camo ground blind is a good idea as well. Animals just don't pay attention to it but another hunter can see it from afar.
