Romex and EMT in Attached Garage

Hi again, I have a question about running Romex in EMT in an attached garage for physical protection. I am wiring my attached garage, following the advice that I got in a this thread: http://www.doityourself.com/forum/electrical-ac-dc/534842-advice-wiring-built-garage.html I now have a dual phase subpanel, and I need to wire outlets and lighting. The walls are finished, so I am planning to run EMT to external boxes. Could you guys help with these questions? 1. Is my attached and finished garage considered a wet location or dry? How do I know? The only garage outlet that came with the house is GFCI-protected.
