I have to say that ALL NPCs have "national name recognition". There are only 26 of them, after all. Just because a GLO isn't on your campus, or even big in your geographic area, doesn't mean they aren't important. It's rather dismissive to say the only glos that matter are the ones you know.
Like Vandal Squirrel, I think it is important to know all the members of your GLO umbrella group - and others, as well. Heck, you don't even have to google it - just go to
