Bret,

Yes, you can bring Tiger data into GRASS.  Get
<ftp://moon.cecer.army.mil/pub/grass/incoming/tigerscripts.tar.Z> for
some scripts (which avoid RIM).  As to the source of the data, you
could always buy the CD's from the Census Bureau.  However, they're
sort of expensive (IMHO), so if you're cheap like me, check out
<http://cedr.lbl.gov/cdrom/doc/contents.html> where lots of the Census
CD's are online.

Hope this helps.

Bill.
