I'm surprised when I walk right into yet another abandoned hunters' camp. Tattered plastic sheeting still hangs askew here and there. Blackened aerosol cans of Cheez Whiz sit in the fire pit, which sits in the middle of the trail. Assorted Styro-ware. Rotten leather boots. Where are these people? Are they back in civilization now, appearing to all observers to be as normal as pie, but inwardly ticking like time bombs and spreading their hot poisonous seed through the world like black-breathed plague?
