?'s about Colorado

I am just starting NS in Jan so I've got some time to research a relocation. Currently I live in AZ and am really getting tired of the heat!! That and housing has skyrocketed, my electric bills could feed a small country, and the school system is one of the worst in the US. I'm considering moving to CO after I graduate. I've lived in Aurora a couple of times and my parents used to live in Boulder so I"m familiar with CO, but it's been a while. Right now I'm considering the Fort Collins area, my dh and I are going out there in July (school break) to look things over.
My main concerns are:
Schools- how good are the schools, I've got a 2.5 yo, 5 yo, and a 7yo, add two years to their ages for when I graduate. Right now my 7 yo is in a fantastic school, but when she finally gets to high school, there's not many good schools.
Cost of utilities- We're paying over $500 a month just for electric from May-October, for a 3500 sq ft house.
Hospitals to work at- I'll be graduating in Dec '07 and need to find a job that accepts new grads
Overall- just a good place to raise kids.
Thanks for any help,
Keli
