Good stuff. We can't wait to go. We went to Needles and Arches last summer and I only had a Dslr. Now, since getting back into shooting film (mostly bw) I've had to think about more that one cam. I agree about the 645. I only have the one 120 back for it. I have two 220 backs for the SQ (which I shoot 120 in) so I could shoot color too. I also have a good selection of filters. And, I do want to shoot some 135 too for more people/street stuff, if it comes up. I will add a dry bag to the list. I have a couple.
Great story about falling in love at Zion.
