One of my favorite parts of going to Howl-O-Scream is looking at the massive graveyards that are usually on display. This year wasn't as good, there was one pretty decent sized one, but it is usually a lot bigger (a few hundred tombstones). A lot of the stuff this year was geared towards younger kids, which explains why a lot of the tombstones are outlined with orange lights.
I think this is one of the reasons I like to have so many tombstones in my haunt. I should have close to 50 this year in all.
