(Reuters) - Fireworks explode over the Olympic stadium during the opening ceremony of the Athens 2004 Olympic Games, in this file picture taken August 13, 2004. The rate of decay and dilapidation of Athens' Olympic venues in just eight years provides a visual clue to maintenance costs too high for near-bankrupt Greece to operate. Back in 2004 when the Greeks staged the Olympics, the country was crackling with optimism, pride and activity, as it rushed to deliver the multi-billion dollar Games organisers hoped would boost the country's growth and its modern image abroad. These days, however, Greek athletes must be satisfied with a trickle of money as they prepare for the 2012 London Olympics, the debt crisis having dried up almost every revenue stream for sports, public or private.
