Last week, the local newspaper reported that "experts" believe that a major contributing factor to the Interstate 35 bridge collapse in Minneapolis can be attributed to pigeon dung on the bolts of the bridges superstructure ... yes, experts actually said this. I work with copper, aluminum, brass, bronze, stainless steel, and iron on a daily basis and have yet to find a naturally occurring animal excrement that possesses the corrosive properties to compromise the strength of any of these metals ... if there was one, I'd buy it to loosen rusted and frozen parts. For those who may still think there is actually some credibility to the pigeon theory, look no further than
our county courthouse. Let's face it, bridge inspectors didn't do their job ... period. Boy, the things people will say to point the finger elsewhere when they caught with their pants down ... pigeon dung, that's the best they could come up with???
