A couple of weekend injuries remind me once again why I travel lightly. First, I pulled some back muscles in a whitewater accident on a North Carolina river. Then, within two hours of arriving at home, I slipped and fell on our stairs in a pair of slick socks. The result is lots of pain and temporary disability. I worked today for only a couple of hours and stopped at a cafe to book some flights. If the lightweight Tom Bihn bag on my shoulder had carried anything more than my sub 3-pound netbook I would have suffered even more. Had I actually been traveling I would have been in major trouble. If your back’s not great, cut the weight! As I get better the posts will increase.
