Rudeness in the Crops?

This is my first ever attempt at a Google Earth kml file. It's not spectacular, I'm just finding out how to use this thing properly.... there has to be a tutorial already written out there! Here's the file, and it requires you've installed Google Earth already. Save the file, keeping the kml extension, and you should be able to double click for google earth.

If your browser is correctly set up, a doubleclick may work.
