This bridge in Breckenridge Park in San Antonio isn't what it seems; in fact, it's made from concrete! By the way, the photographer wasn't drunk - the bridge does tilt like that.
Note: a low resolution printout won't be entirely satisfying. Even the high-res printouts leave a lot to be desired, compared to the original photograph.
