As Mumbai prepares for Ganesh Chaturthi, Ganapati Mandals have been ramping up security and insurance, with some places insuring their idols for as much as Rs. 300 crore. The GSB Seva Mandal in Wadala, which bought the 300-crore-insurance, has an eleven-foot idol, with gold plated hands, adorned with silver and gold jewellery and is the richest mandal this year.
