Ok.  I've checked out the first link but it pretty much just leads me to the
second link.  The second link, the deli, has a lot of 24k DRG maps, but
without the collar.  From what I can learn, it appears that the collar
contains the coordinates of the map.

I've tried the mapfgd.pl script (mapfgd.pl
/usr/local/share/xastir/maps/topo/mn/*) and while it doesn't return any
errors, it also doesn't generate any .fgd files.  Xastir sees my .tif files
in the map chooser but won't load the maps.

Are these maps usable, or will I need to bite the bullet and buy the DRGs (I
have searched and searched but can't find them elsewhere)?

Thanks for the help!
