Miranda Lambert - Airstream Song Chords & Tabs

This is my first shot at this. I'm fairly certain about most of it, but the bridge 
is where I have no idea. PLEASE CORRECT ME! I know it isn't quite right (the Cadd9 
- Em), but I can't figure it out. Help!

Capo 3rd fret

G
Sometimes I wish I lived in an airstream
G
Homemade curtains lived just like a gypsy
Cadd9                           G
Break your heart, roll out of town
D                  Cadd9       G
Cause gypsys never get tied down

G
Sometimes I wish I lived on a mountain
G
Drank from a stream instead of a fountain
Cadd9                          G
I'd stay there, top of the world
D                Cadd9       G
But I was born a red dirt girl.

Cadd9
Unbrideled, or tethered and tied
Em
The safety of the fence or the danger of the ride
Cadd9                     D
I'll always be, unsatisified

G
Sometimes I wish I lived by a pier
G
in a lighthouse with a chandelier
Cadd9                            G
I'd watch everybody's ships come in
D                 Cadd9        G
And then I'd sail away with them.

Cadd9
Unanchored, in the storm or
Em
Safely, on the shore
Cadd9                                   D
If this is all I need, why do I want more?

G
Sometimes I wish I lived in an airstream
G                       Cadd9      G
Homemade curtains lived just like a gypsy.
