Gravedigger - my last (literally) minute prop last year thanks to help here.
My MIB. This isn't the final video showing all the tweaks, but it's good enough. The reactions to this prop were awesome. Click the photo for the video.
It rained ALL day Halloween 06. It literally quit as the first guests were arriving. I had to keep the MIB near the garage so I could wheel it in and out. Sadly, for some reason, I didn't get another picture of it outside.
My first real prop... I have changed it a little each year, but I think I just make it worse.
The very first things I ever built were how I found this forum... a pvc/wood fence and styrofoam tombstones. I built two sections of fence the first year and have added several since then. I build a dozen or so tombstones the first year, and have been lazy since. I did retrofit them to be thicker and repainted them, but I have not made new ones. I bought a bunch at a sale, though.
