AUTOCAD USERS: AutoCad will not recognize the GIS shapefiles that are downloadable
from this page. However, if you have either Autodesk Land Desktop or AutoCad Map, you
can import the files in the following manner:
From the 'Map' pull down menu select 'Tools'.
Click on 'Import'.
In the dialog box, pick 'ESRI Shape' and choose the file you wish to open. Select
the defaults for the remaining questions.
