Here's a map showing those properties I've visited (green with a check), those I haven't visited yet (yellow with a dot), and those that closed before I could get there so I can never visit (red with an X). You can zoom in using the Google Maps controls in the lower-right corner, and move around by click-dragging on the map.
   

   
If you hover the mouse pointer over a property, its name will appear. To see everything in a list, vist my Hard Rock Checklist Page.
