Birthing Center

Bunny
Is anyone having or thinking about having their baby at a birthing center as opposed to a hospital?  I love my OB but I'm trying for a natural birth and I'm just afraid I won't have a lot of say at the hospital.  On the other hand, it's my first baby and maybe I should have him in a hospital, just in case anything goes wrong?  Agghh idk!! Any thoughts??
