Meeting up at San Francisco and Oakland airports, Kathleen, Zoë, Abby and I made a quick refresher course in California backcountry skiing.There was sun...and snow...and vistas (and martens).We're very careful, of course.I remade acquantance with some of the amazing arboreal mountaineers of the Sierra Nevada, such as the Lodgepoleand sociable Western cedar.Having used up the fresh pow, we put on our racing suitsand headed back to bicycle land.
