I would almost certainly expect a Denver show, and that's when they'd hit Arizona. My guess would be a few nights off after three straight nights in Tejas, followed by the SW stretch.
One thing that might screw that theory up is that they seem to avoiding GA venues. The place they've booked here is 3x bigger than what they can sell, but fully seated, and they passed over a couple of appropriately sized GA venues that they would have packed. Seems like where they usually played in Den was a club.
