Thanks for the welcome MHooch, I'm finding everyone one this site helpful and pleasant!

TheWorstWitch; for my tour of our neighborhood, I would recommend looking for anything quirky in your neighborhood because at night you need to do little at creeping people out. I created a myth about an old farm house that happens to be by an old cemetery. The people who live there like to grow flowers and then put them out in a cup on an old rickity wooden stand that has a faded painting of a lady in white with flowers in her hair. They have a sign that says $.10 cents a flower so I just incorporated it into my little fable. I didn't have to do anything but bring my guests by the little stand and let the moonlight cast shadows over the flowers and the "white lady's" face. I told them details of the family that settled the farm and that the white lady still haunts the house today. The only way the family can appease her is by offering flowers to passers-by who purchase a flower to bring to the white lady's grave, in memory of the woman who settled the land. They were told some personal details about the white lady and that she herself was a botonist who loved trees and planted many in the cemetery that was once her farm land. I then took the guests into the cemetery(I made sure it was ok first) and made them identify the three old trees that the "white lady" herself had planted near her stone. They used flashlights to find her grave and offer a flower to her.
(I picked the name on a very old grave that looked unkempt so as not to offend anyone who might visit (and then after the tour I removed the flower) but the guests didn't see because they were too busy looking for catalpa, birch and oak tree leaves to finish their task in the cemetary. When we were on the tour, people were looking at me like little kids who believe what they're being told even though it scares them. And when were were done with the rest of the tour they all commented on how much fun they had and talked about the characters i told them about as if they were real.
No one ever questioned if it was real until we were back to the house and some people were freaking out about the white lady following us home.(Amazing what your own imagination can trick you into seeing, as I didn't have anyone in costume to follow us home, though you could if you wanted to) I let them freak a little while and then told them the deal I've just told you. Oh and at the end of the tour we ended up at our local neighborhood bar where they had to go in and ask about the bartender named angelo who really is in the guinness book of world record 's as the current bartender who's been tending longest. Because our party theme was superstitions they had to ask for Angelo and ask him if he believed in superstitions and if so did he have any good luck charms that helped him tend bar longest. The guests got a rise out of walking into a bar in costume and meeting a world record holder. After they were done with the tour, their reward was to grab a drink, shoot some pool and then head back to our house for the rest of the party.

So my advice is do a little research in your neighborhood, everyone has a story to tell and is interesting in some way. Look for something quirky and tell some fables, but then also find something interesting and true so then they won't know what is real and what isn't...to me uncertainty is the best way to scare adults. We all like to think we have everything figured out...wah ha ha!
