If it involves fresh air and the threat of bodily harm, Steve Casimiro does it: skiing (50 days a year), mountain biking (120 days a year), surfing, skateboarding, climbing, backpacking. Makes you wonder how he has time to be a contributing editor for ADVENTURE (see his and Scott Willoughby's new guide to skis and snowboards) and to write and photograph for Outside, Men's Journal, Skiing, and Powder (where he was editor for nine years), among others.
