En route we came across a group of 3 or 4 men putting up wires to the higher buildings of the rice terraces. They were happy for us to photograph them at work and as the rice terraces were not in their 'glorious green' at the time, the people added colour and character to the scenes'.

This meant that it was up to our rishikumars to finish building the path. After a lot of messing around, they finally completed it and the whole place was finally finished'.

Very popular with the local lizards too when the sun gets up a bit more'.
