Orange, on anything means No Trespassing.
Just sayin’.
Montanans don’t take kindly to folks walking around on their land.
Ask first before crossing into or onto suspect properties.
It is your responsibility to know where you are at. If you are on public, or private land. It is your responsibility.
Orange painted on anything qualifies as a No Trespassing statement. Texas? Purple Paint is the color. Not less than 50 square inches is the rule, but that landowner with his sights on you may not be all that concerned with the actual size of his orange markings.
None of that bullshit like, “Well nobody told me?” That does not fly here, anywhere.
Take responsibility for yourself.
