This turned out to be excellent road-trip knitting. Before we left, I prepared the yarn (weighing and measuring) and popped it into labeled ziplock bags with a corner cut off for the yarn to feed through. Each pattern segment was easily memorized and worked until the next stop, when I could learn the next segment. Aside from a tragic incident with a bottle of ginger ale in sub-zero weather, which will make washing it before blocking more than usually necessary, it is going really well.
It's very near the end, but I am doing some test-knitting with a deadline, so that comes first (and is going fast). Then I will finish this. Then I will decide which to keep and which to give to NKD, since they are very similar colorways.
