I haven't done it yet, but word from several aquaintances in the local cycle club say Kitt's Peak is open and quite a lovely ride now.
I did Madera Canyon earlier this year, and it was quite the slog: It's not steep at all, but it's just a relentless interminable road with undifferentiated features on either side for miles...and then a short blip at the end. If you're going up into a headwind, prepare to be demoralized
