The rusty old bus skids to a halt with a screech of brakes. The diesel engine stops with a harsh sound. Exhaust fumes are winding into dark clouds. It is a routine picture with this bus. There is plenty of room for controversy as to whether it can be called a bus. It is little bigger than a minibus and much smaller than an ordinary one. It has a turtle neck. This grotesque shape is made by a local carpenterDilu Mistry. His name is so strikingly inscribed on its body that it must tickle your fancy on sight. But this optical attraction flees through the window when you get on it through the narrow door in huddles. Jampacked with passengers, it moves at a snail's pace and takes the whole day to cover the distance of about fifty miles between Rangpur and Gaibandha, suffering at least a couple of mechanical failures. People call it a buffalo cart, but they are left with no better means.
