Deer will feed next to a busy road and the cars won't bother them. It's when one leaves the road that they come alive. If they're used to atv's on the mountain, they'll largely ignore it as long as it follows the same trail each time. They have to get used to them being around.

“In a time of deceit telling the truth is a revolutionary act.”
― George Orwell

It's not over when you lose. It's over when you quit.
