Short Hike Syndrome should be (c) Teslinhiker from now on, it has the ring of truth. (fully equipped) daypacks should be like seat belts, you just get used to putting them on and you feel naked without them if you don't. The only time I don't hike with one is on a quick 2 mi run up nearby Rattlesnake mountain, which averages 40-100 hiker per hour it seems, and that's often when I really wish I had my gear, especially the FAK, for kids who fall down etc.
