Seriously, though, Google Maps is, in my opinion, the easiest and best mapping package out there.
Try it out for yourself at maps.google.com.
You can search for a location or get directions. If you choose satellite view you can zoom in and get a top down view of nearly any location. If you choose street view, you can actually see photos of the streets and the buildings along them. Look up your own house address to see what you can see. It is pretty amazing (and a little freaky.)
