  I'm missing something simple here and have not found a man page or other
explanation about the missing step.

  The source file is in standard format with long/lat points. The target
location is the Oregon state standard projection and coordinate system: NAD
1983 HARN State Plane, Oregon North; FIPS 3601 Feet Intl. and Geographic
Coordinate System: North American 1983 HARN.


Maybe I'm not following your workflow exactly, but...
Did you first run v.in.ascii in a Long/lat location?
Once you have the vector map in a long/lat location, then switch to your Oregon HARN 1983 Location and then do v.proj.

  When the source .txt file in in the target location/mapset v.in.ascii
imports it but it is still in long/lat coordinates so I moved the source to
a new mapset in the Oregon long/lat NAD83 location (which is the target
projection and coordinate system (unless the HARM adjustment changed
things).

  Importing the source .txt file into the Oregon-ll83 location's project
mapset with v.in.ascii gave me a vector file in x-y coordinates.

  Restarting grass in the target location/mapset I ran 'v.proj
location=Oregon-ll83 mapset=4247.01 input=proj_bnd' (all on one command
line).

  However, when I try to overlay a much larger LiDAR raster file with the
proj_bnd vector file the do not overlap which means the reprojection was not
correct.

  The vector file bounds are:
    N: 575450.6    S: 573920.8
    E: 7532700.7    W: 7531630.3

  The extent of one of the raster files is:
    634966.8 - 664969.8
    1240513.2 - 1286590.2

  My web searches and reading the grass doc pages did not show me what I've
done incorrectly.

  Advice needed.

Rich
