I've found that the resolution on Mapquest (you have to click on "Aerial Image" at the top right of the map, then zoom in) is usually better than on Google earth.
Google's resolution changes from area to area. And I noticed lately that the images have been updated, but now they are summer scans, where before they were fall scans. The difference being you can see a lot more whith no leaves on the trees. Doh!
