Maybe everyone has seen this...I'm often the last to know cool stuff.
If you have not seen Google Earth, go here and download it. Astonishing, beyond compare! Be sure to fly through the Grand Canyon and learn how to fly down your own street or sail your next distance race from 1000 feet up. Be sure to flip switches and read the travel forums. I spend too much time on my computer as it is but now I may NEVER get any sleep. This thing is addictive.
