If you are interested in yard haunts, I highly recommend visiting www.davisgraveyard.com. They have gone all out transforming the front of their house and yard into a cemetery - with clever sayings on the gravestones and beautiful crypts and monuments. There are galleries of photographs from 2002 to present, as well as new articles and project descriptions. It's easy to navigate around the site.
They are located in Milwaukie, Oregon - and if you're nearby, it looks like a visit in October would be worth your while.
