Yeah, maybe six went up in the tower. Some wouldn't go up at all--the structure was making noises, clanking and popping. I supposed it was strong enough for a temporary structure and went up to the upper platform. Somebody--a heartsick lover probably--jumped from the upper platform the next day even though fencing had been installed to make it difficult.
Good Lord ! This place is the favorite suicide place for some guys. Apart from that - and the occasional sky-diver - the Tower is really safe. But since it's a metalliuc structure, I suppose temperature variations can cause a lot of metallic noises.
