Best route - Texas to Wyoming

I've "cut the corner" from Ft Collins to Laramie many, many times. It's not a bad road, and there are a fair number of passing lanes as I recall. It has claimed a few lives, however. The worst part of it for me is getting through Ft. Collins to the highway. I've always had something else to do while in Ft Collins, so had to approach it from... the mall! ;)

My son and daughter both attended UW in Laramie, so between the two of them, we made a lot of trips that way when going to or coming home from Denver.
