I'm willing to bet the lair is in Beaverton or one of the other suburbia wastelands of strip malls and mini vans that surround PDX. If the lair was actually in PDX the commander would have better things to do than sit on the internet all day and talk smack.
In fact... I bet commander is a stay at home dad Ms Cobra Commander must wear the pants, or in this case the mask, of the relationship
Hey Cobra! What's for dinner?
