They drove for a cause. One team drove to break menstruation taboos, another fairness myths and yet another protested attacks on doctors.

They rallied through the streets of Calcutta, solving crossword puzzles and fitting jigsaw pieces to hunt for treasure. All this and more were on Sunday’s to-do list for the 85-odd participants of Wonder on Wheels, in association with The Telegraph.

The women’s car rally was flagged off at Quest mall at 7.30am on Sunday by Raveendran Sankaran, IPS, inspector general, Central Reserve Police Force, West Bengal circle, and the chief guest for the occasion. This was the third edition of Wonder on Wheels organised by Calcutta Park Street Ladies Circle 46 and Calcutta Park Street Roundtable 34.

“This was a fundraiser. The entire proceeds from the event will go towards education of underprivileged children,” said Ruchi Agarwal, the chairperson of Calcutta Park Street Ladies Circle 46.

Eighty-five cars, each of which had at least one woman member either at the wheel or as navigator, took part in a Time-Speed-Distance (TSD) rally that ran from Quest mall through Salt Lake to Handloom Cottage, Kankurgachhi.

“The rally covered 30km and then the treasure hunt started. The participants were given crossword and picture clues and jigsaw puzzles as clues. They had to solve them to reach the destinations for the treasure hunt. The hunt took them to Columbia Asia Hospital, GST Bhavan, Birla Mandir and Carnival cinema,” Agarwal sadi.

All the cars returned to Quest mall at the end of the rally-cum-treasure hunt with a total run of 55km.

The participants showcased their causes with their attire. “Each team had a cause, and were dressed for it. Like the team that sought to break myths about fairness had shades of black on their faces,” Agarwal said.

A doctor duo appealing against attacks on medical professionals had bandages wrapped around their heads and stethoscopes around their necks. Their message: “We serve you, so please don’t hurt us.”
