The "sea of red" that arrived in Mumbai yesterday reached the Azad Maidan before the crack of dawn. At least 50,000 farmers walked through the night, for five hours, so that students who will be writing their Board exams today aren't inconvenienced. A lit-up Chhatrapati Shivaji Terminus provided a spectacular backdrop as the farmer contingent, swelling by the day, marched to the tunes of folk songs to keep the cadre motivated.
