Study tours are strange things. I’ve been doing them since 2002, but I still find myself caught in the same conundrum every time. Part of me is in teacher mode, thinking about learning objectives and assessment deadlines. Another, completely different part of me is in traveller mode, thinking about what camera gear to take and how light can I really pack and still look professional. My record is 6.2 kgs for a month in Nepal; I wonder if I can beat that in China?
