Some of these pictures have been taken near Kamshet and some near Diwekarwadi, areas around Mumbai, India. The first one is shot near Diwerkadi, in a rural area. A man is using a whip to drive the bulls and another man is sitting at the back. The cart is carrying long sticks as well.
This picture of a young boy riding a bullock cart was shot near Kamshet, a semi-urban area in Maharashtra, India. The bullock cart appears to be carrying some other material as well.
This is a couple with another man near Diwekarwadi. It is in a rural area where this can become the main mode of transport. If a family owns one, why travel in a bus? For short distances a bullock cart is fine!
This picture was taken on a country road. A man sitting in his bullock cart, ferrying some wood to a destination. Another village nearby perhaps. Or to his own home.
