Cool idea, Dan! Boy, the topo lines sure suck on the 2012 topos when compared to the 2004 print equivalents. I assume the 2012 versions were digital/vector downloads, correct?
I was initially excited when I heard that the USGS was making vector maps available to the public, but then, after digging around, I saw how less detailed they were. I imagine they'd be more up to dates for roads at least, though I haven't compared.
That FS map is quite a download!
