Boats docked in Tai O, a fishing village on stilts on Lantau Island, Hong Kong.
I almost didn't make it to Tai O, as I was a hurting puppy during my last days in Hong Kong. I camped on the beach at Pui O for the week and one day hiked from the beach to Sunset Peak. All was well until I started going down, stepped wrong, and blew out my knee. I couldn't step down so I had to walk back to my campsite, 6 km away, backwards. Eventually I made it and rested the remainder of the day and drank as much water as possible. The next day, I woke up with, what I would learn to be, an upper respiratory infection. That day was not fun, but I didn't want to waste it, so I forced myself to feverishly limp around Tai O.
What's the worst injury you've gotten while traveling?
