This is my second year of doing a yard haunt. My "big" project this year was building a version of Trash Can Trauma, of which, I'm about 95% done with. My other props include several store bought tombstones (enough that my wife rolls her eyes when I pick up more), a couple of green flood lights, a Wal-Mart groundbreaker, a little skeleton, and what I call "The Greeter" though most people think of him as the Grim Reaper. I also built the $20 fog chiller this year and need to test it before Tuesday.
The Other project I'm trying to finish up are a quick corpsing of a Blucky.
