Before leaving Dharmsala, Martin had one last chore to do, which was to go to the post office and mail home two huge stones (geodes) that he bought off the street near our hotel. What possessed him to go and buy stones in India the day he was to leave on a bicycle ride, I don't know, but he did it. They were nice enough stones, but they weighed about 20kg (thats 45 pounds). And I experienced the Indian postal system years ago, and unless things had changed dramatically, I knew this would be at least a two hour ordeal.
