Just experienced a camping first. Heard a rhythmic scratching sound during the night, and wondered what sort of wildlife would make that noise outside my tent. Then began to 'feel' a rhythmic pulse under my pillow. MOLES. We stayed 4 nights. Any longer and we probably would have collapsed into the maze of feeding tunnels they were busily working on.
Was a bit freaked out at first, but sort of got used to it. At least, it was ok when the ground wasn't moving!
