"The two biggest I see are bowhunters not announcing themselves when I walk by them. (You shouldn't be bowhunting during firearms or muzzleloader season, much less with camo on. Btw, deer don't notice hunters orange. They notice movement, not color.)"

That's a rather high and mighty statement telling people what they should and should not do with a certain weapon when most of the time it's perfectly legal to hunt with a bow during firearms season even if you have to wear hunter orange while doing it! As far as your other statement, do you expect everyone to hunt out on a range so they have a good backstop? Common sense dictates to know what's in the area, but to say you need a backstop isn't going to happen 99% of the time when in the field hunting.
