I know some rural docs who still do obstetrics. Two of them even have their malpractice insurance paid for them by the hospital they work for, because the need for docs who can do deliveries and have a shortage of OB's in that area. I plan on doing an obstetrics fellowship after my fam med residency, just because I have fun doing OB. It might be harder to find a job that allows me to practice OB, but I want to live in a rural area anyway.
