I've wasted the last two evenings looking at satellite pictures using NASA's cool World Wind software.
Download it; it is just too cool. I've "visited" Niagra Falls, the Florida Keys, Las Vegas, my basic training barracks at Lackland Air Force Base in San Antonio, the Grand Canyon, the Golden Gate Bridge, Rich's cabin in the mountains (you're found!), Vail, New York City, my home in York, the cabin at Pine Grove Furnace State Park, Pole Steeple, Stone Mountain, and tons more.
Cool stuff. I feel like John Ashcroft!
All The Best,
