Here is another aerial photo site that is fun to use. http://www.terrafly.fiu.edu/ Be patient. It is slow to load even with DSL, but the images are seamless and very large, and you won't get lost like you sometimes do with Terraserver. When the FlyFrame image appears go to full screen and click near the edge of the image to "fly". Click on the "?" for instructions. For practice, start at Oregon and fly up the river to Byron. Flying is free, but there is a small fee to print an image. Ann Sullivan
