One other short note about Google Earth if you're thinking of downloading it make sure you have the real, "one and only" Google Earth, and maybe Marty knows some more about this. There are so many subjects now having Google or Googlearth or something similar in the name that its difficult to get the right one without a third party grabbing you and making you pay a fee for their service. Google Earth is supposed to be free I think, or was when I downloaded it years ago. Don't use Google Maps, it's not the same..
