Seeking Correctional (LVN) Nursing Information

Hello to all fellow nurses!
I just received my LVN license this month (january 8th, 2009-yay!) and have found correctional nursing interesting. My grandfather retired as a CO at Rikers Island in NY. I live in central Texas in a military community(Fort Hood). I would like to know have any of you ever worked or work now, in a correctional facility, and if so, how is it-as far as skill experience, benefits and pay, and safety(i'm a female) I do have past medical experience-I was an Army medic, phlebotomist, I also have worked as a medical assistant and nursing assistant. I have an interview Feb 9th of 2009!! I applied for the part time and the prn positions because I'm taking online courses for prerequisites for BSN...
Any information would be excellent.
thank you!!
Kim
