Answer:
My guide, a journalist and environmental activist named Brij Khandelwal, was skeptical. The river was low, he said; there may not be enough water to float a boat. But he was game. So one morning, we met in downtown Agra, a city of more than 1.4 million people, near a decaying sandstone arch called the Delhi Gate, and headed for the river, dodging vegetable carts and motorized rickshaws, kids and stray dogs. Sometimes drivers obeyed the traffic signals; other times they zoomed through red lights. We crossed the Jawahar Bridge, which spans the Yamuna, and made our way into a greener area, then took a turn where men and women were selling repaired saris on the side of the road. Eventually we arrived at a spot opposite the Taj. There we hoped to find a fisherman to take us across.
