Great photos! Sometimes you gotta love big ticket science. See:
http://www.wired.com/wiredscience/2009/10/gbt-nrao-tourDid you know there is a 13,000-square-mile National Radio Quiet Zone? I have read that a guy who works there spent all day looking for a source of noise, and found it was a sparking heating pad in a dog house, in a farm owned by an elderly couple. He bought them (or their dog, actually) a new heating pad.
