I would like to reinforce a DEM with the nhd flow lines, but only at
road crossings.  I have isolated an area and set the computational
region to this.  I have run:

r.carve --overwrite rast=master_mbhw_mb_6 at PERMANENT
vect=srs_nhd_flowlines_2010 at PERMANENT output=mb_conditioned width=1

in grass 6.4svn (last week)  on a 1m DEM and there is no difference in
the output and the original (r.mapcalc difference map).  What should I
look at?

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
