Hi, all ... just joined the tribe. I'm Trevor. Definitely into the idea of spooky historic places. I grew up in Pasadena, and live up in Altadena now. Reading through this whole thread, I have a couple things to add:

I've been in the basement of the Castle Green. There is a story residents there tell about a girl who died down there, and that her spirit still inhabits the various rooms where guests' luggage used to be stored. Didn't know about the tunnels under Raymond. And what's now Stat's is what's left of what used to be the MAIN hotel. The current Castle Green was a smaller annex they added to the original Hotel Green. I think the coolest feature of the Castle is its rooftop penthouse, with an entirely glass ceiling. I was up there back in the late 80's, when the penthouse was available for rent. Totally cool setting.

I've explored the grounds at the top of Lake a lot. Never realized any of it wqs haunted, just historical. I don't think there's any real danger there at night, and have passed through returning from hikes that went late. It's definitely worth a trip, and I'm sure the spirits will emerge if we encourage them.

I've got to go check out this gravity hill concept. I live near that section of Loma Alta, and have driven it in both directions many times. I've never noticed any weird gravitation, but I wasn't looking for it either....
