One of the coolest sites I’ve found on the internet is the free Google Earth download. It uses satellite images and you can see almost anywhere on earth. I really enjoy being able to check out distant places with out leaving my house. You can go to Rome for instance and check out how it looks. I really like the street level feature where you can turn the camera around for a 360 degree view.
I found the system very useful as well. I checked out my own neighborhood to gain a perspective of where things are near my house. This gave me the ability to plan out my bike rides and to take advantage of shortcuts I’ve found! I think everyone should check out this awesome site!
