One tradition we enjoy in my household is browsing the stores and exploring the new costumes that are on display for the season. Halloween costumes have advanced over the years. It's no longer your traditional ghost, monster, or witch. Now the stores are filled with all sorts of movie characters, comedy figures, and more. As a matter of fact, I own a Stay Puffed Marshmallow costume from Ghostbusters where there's an actual fan that runs in the costume to keep it inflated all night long. I also have a life-sized whoopee cushion costume along with a life-sized Kool-Aid man costume. Needless to say, it's fun stuff.
