One thing, probably one of the first 5 things, that immediately caught my attention when we first moved to Mexico had to be the bridges. In Mexico, not every street has a name (or at least a sign indicating what name it might possess). However, every bridge has a name and a sign that is clearly visable. My favorite has to be "Puente Sin Agua en la Derecha" (Bridge without water on the right).
In a world full of uncertainty, what we need are more silly bridge names. Who cares what road you are on, but it's important to know what bridge crosses what dried out ditch that may or may not have at one point had water. It makes me want to go out and dig a deep trench in the middle of our dirt road just so I can have the honor of naming a bridge.
