Not an odd question to ask, but the primary factor of whether or not someone is interested in a guild usually doesn't have much to do with the geographic location of the real world counterparts of the pixel people from the game. If it were me, I'd be looking for people that share similar interests regardless of where they live as (for me) that doesn't matter much when all my interactions with them are through a screen. I suppose there was just some curiosity as to the reasons behind the request though that's up to you if you want to share the importance.
There's a guild in the Boston area made up of college students from the Harvard/MIT/BU/Northeastern communities. They tend to hang out IRL on occasion and invite each other to stuff when not clearing content.
It's not that unusual; but it's not part of what most people think of when a guild is thought of.
