In Aspen, working nonstop on new book. But snuck off on Saturday to “skin” up Tiehack – a local ski mountain – on rondanee or AT skis. What a kick! An hour and a half, going up, with sticky “skins” on a pair of “Alpine Touring” skis. You can walk straight up, because of the stickies. Get an amazing lunch at the top (“Mongolian Stir Fry…” super healthy and tastes awesome, after a hike like that.). Then fasten heels down (with weird bindings) and have a normal ski down. Great exercise. My heart rate well over 80% all the way up…often in the 90′s. Serious hike and so beautiful it makes you grin! Last week, flew from here to the Florida Keys and back (in two days) to give a talk. Sweet life, kids. A little too peppy, sometimes but sweet.
