Took these photos while travelling on a bus in Cambodia just recently. It was raining quite heavily, speed approx 80kph, busy highway with lots of mixed traffic including other buses, large trucks, motorscooters, horse and bullock drawn carts, tuk tuks, kids, cattle and assorted other bits!!
The guys had to sit on the roof as there were about 20 adults & kids inside. The back door in partly opened and tied down to hold the luggage.
A great place to visit, cheap, friendly happy people.
