Jon,

The rr data are in NH state plane coordinates--are the other data you
are using in the same projection?

Thanks Peter,

I had to specify the raster layer as:

LAYER
  NAME "usgs"
  TYPE RASTER
  STATUS on
  DATA o43071a4.tif
  PROJECTION
    "init=epsg:26719"
  END
END

So, I think the answer to your question is, no they're not in the same projection.  What do I need to do to get mapserver to translate between the two? Seems to me that mapserver should be able to read the information out of the files (like ogrinfo and gdalinfo do) and do the "right thing". I admit this might be a total misunderstanding on my part... still learning about mapserver's capabilities.
