I have a quick question:
I am in Phoenix for the month of February, and have always wanted to ride AZ 191 (formerly 666, the Devil's Hwy). It looks like the highs for Alpine will be about 59-60F this Sunday and Monday, and am wondering if there are any contraindications or advice, should I try for it.

Is it better to travel it south-north or north south?

I'd probably try to do it all in one day from Phoenix if possible, as I have other commitments that I have to work around.
