Google docs looks like a very easy way to prepare a document. It has many of the same features as Microsoft Word, so it is pretty easy to use. Also the toolbar buttons are nice.
I played around with Google Earth. I saw my house in Skokie, my house in Wisconsin, and then I looked up Great America. The Great America picture had little post-it type notes that when you clicked on them they told you the name of the ride (they were not available for all the rides) and there was even a camera that when you clicked on that it showed you a color picture of the ride. The satellite view was taken when Great America was first adding the Hurricane Harbor which I think was in 2004, so it isn't completely current.
