Were/are you a fan? Would you stand in 106 F. temperatures to gaze at his (evidently somewhat cheesy) mansion and walk past his grave?
I wouldn't say that I was a gung ho fan even though I liked some of his songs. Nope, I would not stand in 106 degrees for anyone who was not a family member.

Do you think he's actually in it?
Yes, I am sure he would have wanted to be buried on his property; and I think its well protected.
