Most of the people on my bus decided to pass the time sitting in the shade of trees lining the road. In other buses, people stayed inside - and I don't know how. Incidentally, later in the trip, on a bus from Pyay towards Ngapali Beach, I rode in a bus that was crowded like this, the burlap bags being full of onions and the Burmese being loathe to open the windows (they thought it was too cold). That was part one of a bus journey that goes down in the top three of worst journeys in my travel career.
