Personal Information
I am an avid outdoorsman, and have been involved with backpacking for many years. This has also involved rock-climbing, snowshoeing and skiing, to a lesser degree. I am quite adventurous, and have considerable time exploring the Coastal and Rocky Mountains of British Columbia. I have also hiked the Inka Trail to Machu Picchu, rafted down the Grand Canyon, visited the high arctic, backpacked across Europe, and hiked the West Highland Way. More recently, I have taken up caving, with the Cambridge University Caving Club.
