I can’t go to haunted houses as frequently as I used to, now that I have kids, but my husband and I still sometimes do, if we can get a baby sitter.
One really great guide to haunted houses in Portland (as well as throughout Oregon) is Haunt World. You can also find haunted hayrides, corn mazes, pumpkin patches or farms, and ghost tours on that site.
I love how the site has skull ratings for things like “Scare Factor”, “Monstors/Actors”, “Originality”, and more!
