Should I start in corrections?

I graduated in May with my BSN and a dream of being an ER nurse, but my state's horrible job market is making me realize that I might have to settle for something else so I can at least pay my student loans. I've applied to numerous ERs, ICUs, and med-surg positions with little luck. I keep getting told that by recruiters and nurses that they like my resume and would like to take a chance on me, but unfortunately most hospitals just don't have the money to hire new grads right now and really need experienced nurses. Most of my graduating class is working home health/public health/nursing homes or going back to school for their masters.

I have an interview for a corrections nursing position next week and was told by a friend that previously worked for them that I was pretty much guaranteed the position since they're so short on nurses. The pay is comparable to (or better than) night shift hospital pay and the benefits are awesome. I was told by a recruiter that I would pretty much have my choice of facilities too- I'd shoot for the facility that does the most intakes and has an on-site infirmary, that also happens to be in the same city as the major Level I trauma centers for networking purposes. But will I be "stuck" working corrections for the rest of my career? Or do y'all think I could apply to ERs (or even med-surg) floors in a year or two and be seriously considered? Is this even a good environment for a new-grad?
