There’s a great gallery of old underground bunkers over at io9 this morning. I cannot get over this kind of stuff. I’d love to be more adventurous and actually visit places like these. It looks like some of them may even be open to tours.

Here’s a great photo gallery of what happens to Olympic sites long after the games have left. It’s amazing to me that these places have been left to rot after hosting such a monumental event. I suppose I understand however, that many countries can’t afford to maintain many of the buildings, especially for the more “niche” sports.
