I didnt know if anyone had seen this, but I found this while sitting in a computer class... its a satellite that takes pictures of stuff in the US, try putting in your address!
You probably wont find anything past 2002, thats the latest i've found, but for example, i put in my girlfriends address and the trampoline that is in her yard now, was there when the picture was taken 2 years ago.

Hey---just keep it down---I use this to take pictures of my local
teen agers neighbor hood and show them the picture...then I tell
them that their dad has hired me to keep track of them--works so far..
