I do have an office where about 70 percent of my writing gets done, but sometimes it does get a bit stir-crazy to be cooped up in there, so I'll grab my laptop and write somewhere else: another room in the house, out on the patio, or even Heaven-forbid, a trip to Starbucks. But I also write on the road.
