A friend of mine is about to go on a one person multi month trip with his bicycle through South America. Before he leaves, we want to give him a present for his upcoming birthday. The straight forward way would be to ask him, what he needs, but we would like to surprise him if possible.
One idea would be make him a laminated photograph of us and best wishes as a lucky charm. Do you know presents that will be useful and will be likely to suit a bicycle traveler.
