Trail Tech: A.T. in Google Earth

Are you already a Google Earth addict?  You may not realize this, but with Google Earth, you can quickly get a better grasp of the terrain by simply tilting your view (make sure the Terrain layer is turned on). The 3-D terrain is much better in Google Earth since Google added a much higher resolution terrain. 
 
You can get the best of both worlds by downloading a tool which will overlay USGS Topographical Maps into Google Earth for your current view (note: better quality topo maps are loaded as you zoom-in closer). Another thing you can do is turn on the "Geographic Web" layer, which will highlight photos of the regions (even photos taken by hikers) and place-marks to interesting places along the way.
