John,

   I'm embarrassed to write that I did not look carefully enough at the Web
site. I saw that I could order the files I wanted, but neglected to check
format assuming they'd be .e00 like most federal agency data. Mea culpa!

   I know. I've been using v.in.org for the vector data from the Oregon state
GIS repository.

   Thank you ... I'll re-order the data. They put the data on one of their
ftp servers. Oregon data (zipped not tarred and gzipped) is 425M; unzipped
it's 1.1G.

Much appreciated,

Rich
