Maggie Siff is better cast as Rachel Menkin in Mad Men than in Sons of Anarchy as Tara, Jax's "old lady" and doctor.  Somehow she is not convincing in Sons of Anarchy but all is forgiven as everyone else is totalling convincing in this fabulous show.  I believe Series 3 is due for release soon.  Just love the scenes where they are all cruising down a highway full throttle in their individual styled Harleys.  Bring it on.
