In pictures: Journey towards the epicentre

After the earthquake struck Sichuan province, Bill Stranberg, a student in Chengdu, headed for the town of Dujiangyan and the surrounding mountains.

These are his pictures and comments describing his journey towards the epicentre of the earthquake.

"A lot of people fearing for their families were on the bus to Dujiangyan from Chengdu. We got there after dark and the only thing lighting up the city were the lights of the cars driving by and the flashes of cameras."
