Hi Jeff,
You were almost there. You need to set mpAreaMaskingOn to True to
turn on masking capabilities. Also, I changed your outlines from
"GeophysicalandUSStates" to just "USStates" so that the outlines from
the other countries didn't show. You can change it back if this is not
what you want.
Below is a new version of your script. I also set gsnMaximize to True.
This will maximize your plot for whatever output device you use.
Cheers,
