This post started with Ryan sending me this link demonstrating a KML overlay of county borders of his bifurcated state in Google Maps.
Then I found this Roundup of Google’s Geo Developer Day (btw, I so wanted to be at Where 2.0) with tales of the new geocoding feature of the Google Maps API, more details about KML-in-Google-Maps, geotagging in Picasa, and the new Google Earth 4.0 beta.
And somewhere along the line, I ran across a link to SketchUp, Google’s 3-D modeler that seems built especially to put dimensional structures in Google Earth.
