Here's a great website that lists some famous haunted cemeteries around the US.

If you live near one of these, check it out for Halloween (or any other time.) Loads of funs for all---we are visiting the Hundred Steps Cemetery here locally for the Big Night---this graveyard didn't make the list but it's famous in these parts.

I was in a cemetary once on Halloween, late at night, and there was a lovely ground fog that night. It was thoroughly boring.

Hopefully we'll have a better experience. We've been to haunted cemeteries before but not this one, one of our state's most notorious.

If I was a ghost, I wonder if I would be more likely to come out on Halloween, or less likely...

Well I didn't mean just in a graveyard. I meant everywhere.
