I just returned from a 4 day vacation: About 36 hours at the Grand Canyon and 36 hours in Los Vegas, with driving and flying at both ends and in the middle. I couldn't get enough of the Grand Canyon and time went by way too quickly. I couldn't get out of Los Vegas fast enough, and the time simply dragged.
I worked on the clapotis in the airplane, in the car driving through Arizona, and while shivering in the quiet conference center area that I found in Caesar's Palace. I so wished the darn thing was complete because I was cold at the Canyon, and even colder in the casinos of LV and downright frigid on the airplane coming home. Fortunately, clapotis is long enough that it provided some coverage while knitting on the hyper air conditioned plane on the way home.
