I’m doing all three. I’ve got my equipment strewn all over the bonus room, as I’m weighing gear and deciding how light I can go while still being well equipped. I’m trying to get it all down for a possible foray out onto what might be the most intense and difficult trail in all of the United States. It’s called the Sierra High Route, and it basically goes through the Sierra Nevadas from Kings Canyon to north of Yosemite. It's about 200 miles long and half of it doesn’t have a trail. It climbs over so many 10,000- 11,000- and 12,000-foot passes that I’m breathless just thinking about it. Many hikers need a month or more to get through it—my team is looking at two weeks or even less. Like a trip into space, every ounce is going to be critical: routefinding, map reading, physical conditioning is all going to be important.
