Though Sriram remains the numero UNO organiser of heritage walks—he has done over 60 such walks, invariably enriching them with talks—others have been quick to follow. Like Sukumar the CA, who needed little preparation when, in 2013, he put together his first walk around Gandhinagar, the first organised residential colony in Chennai. Having been born, brought up and lived there—in all, over six decades—he knew about every bungalow and its occupant. He can reel out a stream of lively nuggets, like how yesteryear movie star B. Saroja Devi learnt to cycle on the shaded avenues of the colony, or how S. Venkataraghavan used to play on the local cricket ground once. “While most bungalows have given way to apartments, there are tales that successive generations want to hear. That is why the Gandhinagar walk is in its fifth edition,” says Sukumar. The walks are also used to spread messages on rain water harvesting and the importance of maintaining a shallow well.
