Maybe someday they will upgrade this to the Freedom Plaza 2.0. They will do a giant printout from Google Earth of the satellite photos which represent the same area in the map of Freedom Plaza and put it into the Freedom Plaza.

I've made an image overlay to show what I mean. See the attachment. Zoom in to the location of the map within the map again (as low as you can go in GE) and you'll see the original map has been overlayed as well.

It's kind of a recursive map. :-)
