seeking advice clinical nurse specialist

I am graduating in dec and want to go on to an MS program. I am thinking of a clinical nurse specialist. So I have two questions. Where is the greatest demand for them? I live in Idaho and my instructors say that there is not much of a demand for clinical nurse specialists in Idaho. Also I am thinking of specialising in renal. Is this a high demand field? In what field is the current greatest demand for clinical nurse specialists?

Here's my links to ANCC Certification (or at least one of the posts): http://www.ultimatenurse.com/forum/f...399/#post60011

And here are the different Certifications: Certification - American Nurses Credentialing Center - ANCC I believe Renal isn't on that list, but..... take a look here: http://lmi.ides.state.il.us/healthca...Specialist.pdf
Sounds like Illinois has a demand for CNS's.
