A map that shows the highway system of US. It is very interesting that it is very dens on the eastern side of US and very scares on the western side. The US highway system is the biggest public project in the whole world.

This is a map that shows the big forest territories on the earth. This is interesting to me because I can see that the biggest spots are on 2 latitudes (Upper side of US and Canada with Russia, Brazil with middle side of Africa).
