S.W.
I have not had a VBAC but I know several women in Utah who have. I really suggest you contact ICAN (International Cesarean Awareness Network). I think the Web site is www.ican-online.org. The organization is excellent, AND the current president (Pam Udy) lives in northern Utah and is likely to be current on your options here in Utah.
I also suggest you Google the blog "Birth, Babies and Breasts, Oh My!" The woman who runs that blog also hosts a birth discussion group and most of the moms I know who have had a successful VBAC are people I've met at that group. I'm sure there's an email contact listed.
Good for you for exploring your options--you're already trying to make the best mothering decisions you can for this upcoming baby! Best wishes!
