I'm plotting lat/lon, then oplotting some more.

They wind up being line plots.

loadct,13
display is currently set to 16bit
I get a nice rainbow of plots incrementing the color as I generate new
lat/lons
(too much to explain why I'm doing that)
oplot,lons,lats,color=(j+k)*30+200

My nice rainbow of lat/lon trajectories wind up as primarily red with one
orange
