Google Maps doesn’t show county boundaries, so Randy Majors has created a new tool to
display them. The tool is simple to use. Simply enter a place name and then
click “GO.” The normal Google Map commands of Plus (+) and MINUS (-) can be used
to zoom in and out on the displayed map. You can see all county lines on Google Maps anywhere in the U.S., U.K., Ireland, Australia, New Zealand, Canada and Switzerland. You can get more details at
