I enjoy the sport in several forms—ski touring on roads and trails, locally, telemark skiing in isolated backcountry ski bowls and at downhill ski resorts. and snow camping in the Sierra backcountry in the spring. I wrote a guidebook on cross-country skiing called Ski Tours in Southern California. I've been an active Sierra Club member since 1974.
