'Bot and 'Con HQ locations

In the cartoon, do we actually know (or even approximately) where the 'Bot and 'Con bases are located? I've heard the Ark was somewhere in Washington while the Nemesis was somewhere in the Pacific Ocean. I've checked out the TF Wiki, and they say, according to the Fight! Super Robot Lifeform Transformers manga (hell of a title right there), that the 'Bot HQ is supposedly located in Arizona. That, however, is arguable.
So, do we actually know where they are?
