I love messin' with Google Earth. Our house doesn't show up well because the outlying regions have less resolution but the city regions are great. You can see the basketball hoop stand at my sister-in-law's house and two people playing!
At Connie and Wayne's place you can see the cars in the driveway very well and it appears there are a number of folks in the side yard (which is probably us having a cookout). The Soo Locks are pretty neat and you can see several lakes freighters coming in from Whitefish Bay.
The 3-D aspect looks aren't too bad either. I used it to give Wayne directions to a motel where he was staying recently in Toledo. What was cool was that I could reference specific buildings for him as well as the roads themselves.
