We really wanted to see this but couldn't park anywhere (it's in downtown Boston) so we had to drive away sadly.
We loved it! The tour was great, lots of info and the house is well cared for. My kids were very creeped out. We didn't stay the night as my youngest was not old enough yet.
The Rays are near the front left side of the cemetery in their family plot. The cemetery was freshly mowed and looked well cared for when we were there on 7/16/15.
There's no where to park and look at it. It's in a very upscale neighborhood and the neighbors seem very keen to keep people away. Too bad.
I loved it and my kids loved it. It was creepy and awesome.
