The USGS sells a very nice Optical CD ROM with all 50 states that includes
counties, rivers, streams, water bodies, major roads and railroads.
The disk seems to have about ~100 megs of data with  I believe 3 different
types of data files. A PC demo program will allow you to graphically
look at the data you are interested in, and there is on-disk documentation for
the file formats.

I bought my disk for $28 from the USGS office in Menlo Park.

You can also get the disk by calling the Reston, Virginia office: 800-USA-MAPS.
The disk is called: 1:2,000,000 scale  Digitial Line Graph (DLG) Data.
