Zoom to World
To zoom in just click on a spot on the map. To zoom out use the controls in the upper left corner of the map(-). You can also just drag the map to better take a look at an area (just click and hold down the mouse and drag the map).  To get to more detail on an area click on the ballon and click on the link in the ballon. You can use the links above to zoom back out.

 

 

You should be seeing a map that looks like Google Local at this time.  If you are having problems you can check out their help page here.  If you can usually see Google Local and not the map above and you are using Internet Explorer as a browser you can try the tips here.
