A friend of a friend worked on Death's Acre (the one in Tennessee, there are two), researching the effect of textiles, I think. He said that she said it didn't weird her out until one day she procrastinated checking her body, and had to get her day's stats at night. In the dark. With a flashlight.

She said walking through the woods with the flashlight flickering across the corpses was, in fact, freaky.
