One of our fellow hikers has been famously tormented by a mouse. First - at a shelter he discovered mouse feces on his SPOON in his dishes bag.
At the next shelter, the sound of a mouse chewing on something above his head drove him from the shelter in the darkness, only to have the sky open up above him and have him, his cell phone, his ipod, and everything in his tent get soaked.
In a picture below you will see a wanted poster that he produced for the mouse.
GOOD HUNTING MR. DAISY!
