People do have to realize, that in Ontario, there are quite a few more people out hunting on Crown Land, than most other provinces, I mean this is my assumption, but I think there are more people fighting for less hunting land in Ontario, compared to other provinces.
It is fairly conceivable, that someone could be in a ground blind, and there is a deer between it and another hunter 150 yards away. The camo is pretty good, that a hunter might not recognize it as such and shoot at a deer/moose, etc. and the backstop could be a another hunter in a well camoed ground blind! Is it that much to ask to stick a piece of orange on the blind? So someone could recognize it, and not make a grave decision. I am all for personal responsibility, but in this day and age, with litigation being what it is, families of dead people sue. So yes, you might make the decision to not have a piece of orange on the blind, but what happens when you get killed, and your daughter decides to sue the ass off a hunter that took a shot, missed the deer, and hit a you in a ground blind that he/she could not see because it was so well hidden. The deer/moose can't see colour, so what is the big deal?
Like I said, maybe this doesn't apply to different provinces, but Ontario can be pretty crowded with hunters vying for the same space!
