I have heard many many stories about Bachelor's Grove before I actually went there for the first time a couple of months ago. One of the stories I have heard again and again is of people stumbling upon a house in the middle of the woods...maybe the ruins that you found are what is left of it. I have also heard that many people that have found that house have combed Rubio woods looking for it again and have never been able to find it. Just thought that was interesting when I heard you say you found it too.
The first time I went I was really surprised by the heaviness of the air out there, and how heavy my footsteps became. I felt like someone put a back back full of bricks on my back! I started getting dizzy, and was having a hard time breathing by the time we got to the actual cemetery. I went with a close friend, during daylight, and we both felt like we were bring watched the whole time. I tried to only take pictures when I really thought I felt something around, but nothing has come up in any of the pictures I took.
The pond does feel very ominous, and when I first walked over to it I tripped and nearly fell into it. Right afterward I felt like I was being watched from the brush next to the pond, and ran to catch up to my friend...I felt like I was being chased.
We also found a headstone that looked like it had been used as a alter of some sort.
