br Welcome to Obama-nia. As Mumbai gears up for the US President’s visit on November 6, Mumbai’s Radio Club, near the Taj is in a quandary. br The club, which was supposed to host a Diwali Ball on the date now fears it may have to be cancelled because of the heavy security surrounding Obama’s Mumbai visit. With the city turning into a virtual fortress ahead the hi-profile visit and reports pouring in about road closures, no-go zones and heavy security, the organisers believe the Obama visit may turn out to be a literal party pooper for them.
