Athens (AFP) - As the sun rose above Greece on Sunday, young and old were already queuing to have their say in a referendum which could be a new dawn for their crisis-wracked country, or plunge its finances deeper into the dark.Voting 'No' means rejecting an austerity-heavy bailout deal from Greece's international creditors, but it could also see the country forced out of the eurozone, with untold consequences."I'm voting 'No' because I think it's better for the country," said 80-year-old Michelis, first in through the doors of an elementary school being used for the vote in the centre of Athens."If we vote 'No' they'll take us more seriously," he said, adding that he was "not voting for myself, but for my grandchildren" and their future.Prime Minister Alexis Tsipras and his radical-left party have urged people to say 'No' to a "humiliating" deal from the European Union, European Central Bank (ECB) and International Monetary Fund (IMF).But many Greeks are fearful a 'No' vote could see a return to the drachma -- the currency used in Greece before it adopted the euro in 2001 -- and support for the 'Yes' camp has been growing in recent days.Theodora, 61, a retired journalist, said she was voting 'Yes' because "it's a 'Yes' to the European Union"."I pray on my knees for the 'Yes' to win.
