High school here? It seems to be added to this map about 6 years ago. However no satellite imagery confirms this. It would be strange if all of them were over 6 years old

Also, Bing maps shows no evidence of school, and they are just 3 years old (2015). So where did this invisible school come from?

I was headed east on this road. There's a big tall gate here that prevents you from going any further east. It was a study gate though, so I jumped it, hoping to spend a quick minute in somebody's private property before taking the road northwest to Bollinger Canyon Road. Unfortunately, the straight unnamed road here that leads to Bollinger Canyon is entirely overgrown. After about five steps it disappears. It should be removed from the map.
