Roadside Graveyard...

I love cemeteries. I'm creepy, I know. These photos were taken at a rest area somewhere in Missouri. I've noticed a lot of graveyards on the side of the interstates while driving through the Midwest... like just out in the middle of no where! I'm not sure why they're there... maybe there were once towns that existed at and some point, and were eventually abandoned... and then highways were built? I don't know, but the mystery intrigues me. Creeptastic.
