I graduated from UNC's traditional BSN program. I thought it was an excellent program, the instructors are great, very helpful. I would highly recommend it. At the time I graduated, UNC had a 96% pass rate-96% of the students that took boards passed. I think you can check the colorado BON website and they can tell you what different universiity's pass rate is/was.
Greeley has a small town feel to it although it has grown quite a bit. We did our clinical rotations in Greeley, Loveland, Fort Collins, Denver, Brighton so there is some commuting for clinicals (don't know if it is still that way but I would imagine so) Commuting wasn't too bad though because you could car pool and quiz each other on the way to clinicals, and decompress afterwards on the way home. I loved it!
Feel free to PM me if you have any questions about UNC, I'll be glad to help if I can.
