Paul,

For SeeYou I recommend using the .sua file. It treats sua's
TYPE=BOUNDARY data as "Other" in its airspace list, so you can specify
its own color and line width.

If you use the .txt version, it will plot the same as Danger, and if
you have Danger in your other airspace file(s) you won't be able to
turn it off without turning off your state borders.
