Even though I decided to have my VBAC in a freestanding birth center, I know many people feel more comfortable in an actual hospital. In my town my hospital does not do VBACs so I would've needed to travel to find one that allowed them.
Here is a great resource for you if you are trying to find a hospital that allows VBACs. It is taken from the ican website, which I mentioned earlier has some wonderful information. The list shows each state and all the hospitals and then tells whether VBACs are allowed, banned, or defacto. Defacto bans are hospitals that do not have an official ban, but do not have any doctors that do VBACs, or are hospitals that allow VBACs but have not had more than 2 in the last 6 months.
I would still encourage you to ask lots of questions of the hospital that says they allow them, to get a feel how friendly towards VBACs they really are.
