You have aided my dull brain greatly. I was messing around with Google Earth the other day and couldn't figure out what these were (I had the Google Community, etc. off - trying to identify places without help is a fun use of the service).
Try this:
Google earth on your home with greatest magnification. then try to figure out when the picture was taken.
Using some clues I found on the picture I fugured out that:
The picture was taken on a Tuesday (the trash cans were on the street)
The picture was taken probably 9-10 am. (the shadows were pointing west)
The picture was taken over 2 years ago (A truck in my driveway was sold 2 Januarys ago.)
The picture was taken the week before a holiday (my neighbor takes his RV out and parks it to reserve a spot on holiday weekends, and his RV is gone).
With all of the above, I'm betting it was taken right around 1 july 2002 or 2003.
