They spent so much money on these Olympic venues. They thought it would function even after the games. They were wrong. Not long after the Olympic games were held, the number of visitors decreased dramatically. No wonder that they decided to close it down and stop wasting any more money on it. Now it stands here abandoned, because it would cost additional amount of money to demolish it. We're waiting for someone who would buy it as it is. Until this miracle doesn't happen, you have to make sure that nobody sneaks in and risk his or her life, because the place is really dangerous.
