I understand the dislike of seeing flagging while bowhunting, don't use it myself, but I don't think taking it down is right.
Not everyone is good in the woods. Tampering with the flagging might get someone lost or hurt. I agree it's unsightly on public ground. I think I would rather see the flagging than sit in the stand with my bow and watch somebody blunder around in the dark, lost and scared. What if it's a young person just learning to hunt?
It needs to come down after season but if it's not against the rules to use it in the public hunting area, I would think taking them down would be. Just doesn't seem like the "higher road" type thing we talk about all the time.
