@jamesgage7 In your entry for the Stone Castle Powerhouse, you said to watch out for security guards. Is it on private property?

It’s not too clear–there’s a fence around the plot but no visible trespassing signs that I could see. Neighbors are nearby though. There aren’t patrols-- security is called if you’re spotted so if you’re quiet and alone you’ll be fine. Lots of poison oak and the ground will be wet in parts–something to keep in mind. Hope you go to see it; it’s definitely worth it.
