I also live in the Cities but I am originally from Superior, WI too.
I'm fairly familiar with the crap that is going on in the Duluth area as far as the shortage of nursing jobs.
My brother, who also graduated with his ADN, said that there were no hospital jobs in Duluth. When he had first finished school he got his permit and got on as a nurse tech (is that what they're called?) before he took his boards. Once he passed his boards, he would be hired by the hospital. Unfortunately he didn't pass his boards, his permit expired, and he was out.
I'm sorry to say this, but I think that getting an ICU job up in that area would be sheer luck. Have you thought about looking for something else?
I truly wish you luck. It's a tough situation that you're in. There are quite a few jobs in the Twin Cities area, and the pay is a bit more down here too. Come on down!
