Thanks, Tim. Would you still have info to get ahold of Tom Phillips?
Did you use your own vehicle or theirs?
How about snow? Alot? None? How cold?
Used his vehicle - "a lot" of snow is very unlikely. FWIW, at Bryce at that time there was a lot of snow - made the shots from the overlooks interesting, but all the trails were closed. At Zion, no snow. Cold enough that you'll want to layer a couple of thin gloves.
Tom is getting on in years, I hope I have one more opportunity to take advantage of his guiding in the next year or so.
Don't know what your other plans are but the stuff around Page (the Antelopes and Horseshoe Bend) as well as Moab (Canyonlands and Dead Horse Point, I'm not a big fan of Arches, you really need an extended stay to do it justice) would be worth the time as well.
