The country's only serving lady police commissioner, Chiling S Lepcha of Siliguri Police, flagged it off to the beat of a smart police band even as the ceremonial bugle echoed in this quaint hill station.
The five day rally that officially begins on Sunday morning will cover 1250 kilometres, traversing through the three countries of India, Bhutan and Nepal.
They will drive off from Siliguri early on Sunday (February 26) morning and race through the picturesque Dooars area with its lush forests teeming with wildlife and verdant tea gardens before crossing the international border to enter Bhutan.
