Keep in mind that these images you are seeing are not up to date images. For example, where I work (DC area), my building is almost by itself. However, there are a couple other 15 story buildings in the area that are not showing up. Similar issues with my living area as well.
Just stating this because you may find areas that the detail is from years ago (sometimes up to five-ten years depending on the area).
That being said - it is cool to look at areas. Just can't wait until imagry is about 24-48 hours old. Could be very nice.
Dangerous for those who want to attack locations - but still could be nice to look at.
