Its not in LA proper thats for sure. Maybe by Ojai Leave a text comment or send a personal message to the guy who made the video.The person who posted it made the video. They are his dogs.That much land in LA would cost you a kings fortune.
Nowhere in LA itself, probably not in LA county. I m pretty familiar with all the hills and valleys around LA, and that area doesn t seem to be in LA. Probably north and/or west of LA. There are no visible landmarks to identify it, other than the chapparral, and there s about a bazillion acres of that north of LA.
Are you looking at the hills in the farm scene? I would say Southern California, but that doesn t narrow it down. It could be Camarillo s hills, or the Santa Monica Mountains.... I would email the person who made the video and ask them. Good luck!
