Medicine Bow is a cool area but I would not put it on a par with the Sawtooth area.
Only been to the Sawtooths once and loved it. Been to the Medicine Bows many times and love it as well. I did a page on the range on another site that may shed some light on it for you if you're not familiar with it.

Northern Colorado will certainly been within reach, the Winds and the Bighorns will take you at least 3-1/2 to 4 hours to reach, with the Tetons a bit farther out.
Good luck!
