Lyric discussion by cbingham 

JD's friend is in the emergency room because his meth lab exploded (The explosion was what "Your Belgian Things" was about). In a hospital, there are places where nobody is allowed beyond the lobby except for the patients, the doctors, and the nurses. Friends and family are not allowed to visit the patient while he's in critical condition. JD somehow gets in there anyway to get a sneak peek at his friend, hence "I am a mole sticking his head above the surface of the earth." JD is desperate to know if his friend is okay.

I'm guessing that JD wants to take his friend to the desert because only there will they find nobody who knows that they made illegal drugs.
