Steve and Evan, I've been looking back at the old threads. I'm the one that changed the SoCal/Hawaii version to the version you see above. And I know that I never had a vector version of any of these, only the flat jpeg version.

So I can't really do anything to improve what you already have, except to enlarge it or change the format, and I know Evan can do all of that too.

In short, I think the above is the best version we have.
