So, I was answering the Trapped in 1991 post and decided to try something...
Check out this link and tell me what you think it is:
http://maps.google.com/maps?q=1122+W.+Cerm...07607&t=k&hl=en
If your answer is "A satellite image of the site of the Cermak Blast" you're correct!
(You'll need to look just south of the marker)
In particular Seattle is in a pretty good footprint with some great resolution (you can see inside the Seattle dome), so this is a great tool for setting up some runs.
If you guys have already seen this, my apologies, but maps.google.com is just too cool.
