Use the buttons below the map to show where we've been. You can pan (drag) and zoom just like any Google map. Click on the map pins to see the place name and sometimes more. The map pins usually point to the exact building or site (if I could find it), so be sure to zoom in and turn on the Satellite or Hybrid options.
If you are using Internet Explorer and the map is way the heck down on this page, make your window a bit wider and the map will pop into the proper position.
If you have Google Earth (it's free - get it here), you can download the .kml files below (right-click and Save Target, or Save Link) and get a much better view.
