Any advanced practice rehab nurses in Ohio

I am currently contemplating returning to school for my MSN. I currently work in an acute rehab and love it!!! I do have some questions about further education. It's not that I don't love where I work or what I do, but I am thinking about my future as well.

1. I have some Would I be better off becoming a NP or CNS?
2. What area would I need to specialize in (I have not found any rehab specific programs). I was thinking it would probably be adult care or geriatrics.
3. What are your roles as an AP nurse in rehabilitation?
4. Do you know of any good online ADN to MSN programs?
