Countless times I've said, "I'm only going out for a short while. I'll just take the camera out past that bend. I don't need a jacket or water." Next thing I know, it's four hours later, getting darker, and I'm unprepared. I've learned the hard way to always carry a jacket and space blanket, a good headlamp with extra bulbs and batteries, water, and a compass. Some of the most stunning places on earth are also the most remote. They're places of extreme beauty, but also of danger. Be prepared for both.
