When I was a kid I loved looking at maps. As an adult I still love looking at maps. Looking at maps raises all kinds of questions in my head about the places that I look at. I know I'm not alone in this practice because I have spoken with numerous students and adults who do the same thing. The new 3D Tour Guide is perfect for folks like us who look at maps and have questions about the places we see. The 3D Tour Guide answers some of those questions for us. And if you're planning to have students create Google Earth tours, the 3D Tour Guide provides a good model for your students to follow.
