I've let the following script run for 3+ minutes before killing the
process. I don't understand why it's taking so long for only three points. I
must have an error here, despite following the man page and the example it
contains (except that I've not used the '-r' option).
cs2cs +proj=latlong +datum=NAD83
+to +proj=lcc +datum=NAD83 +ellps=GRS80
+lat_1=43.0 +lat_2=45.5 +lat_0=41.75 +lon_0=-120.5 +x_0=1312336 +y_0=0
+nadgrids=WO

Suggestions, pointers, clue sticks welcome.
