This happened twice to me this year during deer hunting. Both times I had legal bucks well within range, but both were within feet of a "line", private/public in my cases. I was probably good to go in both cases, but why risk it

I passed on both, and ended up with tag soup (A 1st for me in 38 years

)
Us humans have very few excuses to not know where any line is, and as ambassadors of the sport we love, should never cross that line. As for the animals, not so positive they really know where the line is, they are prey to some form of predator no matter where they are parked at any given time.
