We are birthing with a MW at a birthing center, 55 miles away. (granted, we live in rural KS, so it is only an hour drive, unless you get stuck behind a tractor ;)
Anyhow, it is TOTALLY worth it, to me, to have my prenatal appts with the person who is delivering my baby. Bonus, I adore my MW! :)
Good luck with your decision, I would definitely call your MW and that way you can calculate just how many appts you actually will be attending. It may be less than you think! :)
