Never mandatory to be on a trail, is very helpful for people with limited internet like @rakkasan84, new family member, who camps a lot and has very limited internet. I like the fact that it says we all kind of approve of the same thing and have no qualms about supporting each other. To each their own. I used to manually do it a lot, but wow, it got tiresome and took up a lot of time so I could only imagine what it was like for other people.

as for the zombies - you don't - they don't stop until they reach their goal - brains!
