AHMEDABAD: When 1.2 lakh people said 'namaste', all at the same time, the sound travelled across the world's largest cricket arena here - the Motera stadium - from the galleries to the ground, and the VVIP zone on the stage.On Monday, when US President Donald Trump began his speech with 'namaste,' the entire stadium returned the greeting together.Prime Minister Narendra Modi 's call, 'Long Live Indian-American Friendship', received a similar response. And, the sheer size of the stadium inspired awe.The stadium was packed much before Modi and Trump arrived at noon as people waited for hours despite the scorching heat.They received a spectacular ovation as they strode onto the stage. Groups from several districts of Gujarat were spread across the stadium. The loudest roar of approval came when Modi and Trump addressed each other as 'friends'. The US President's allusion to Bollywood blockbusters, his 'chaiwala' reference about Modi, and his appreciation of the contribution of NRIs in the US drew spirited cheers from the crowd.For the police, it was a big task. People were frisked by two policemen simultaneously. "This allowed us to frisk each person in just five seconds. Still, it took about three-and-a-half hours for the stadium to fill up," said a city police official.Those at the stadium were provided specially-designed white T-shirts and caps to ensure uniformity. A few groups entered the stadium with saffron jackets with 'Namaste Trump' logo them. Many put on Modi and Trump masks.A participant from Khokhra in Ahmedabad, who did not wish to be named, said that the corporators took him and others in the neighourhood to the venue in buses. "We were provided breakfast before we started for Motera at 8.30am. At the stadium, we were served boondi-ganthiya and buttermilk," said the participant . Corporators were asked to click photographs of groups of people they had brought to the ground.The stadium began to fill up from 7.30am and a host of performers kept the people entertained before Trump and Modi arrived. As Kailash Kher Veena Saxena , Kinjal Dave, Kirtidan Gadhvi and Sairam Dave performed, people broke into a dance.
