US-Mexican border from Mexican side near Puente Paso del Norte (some Mexican people still call it Puente Santa Fe, but it is well known as Puente Paso del Norte, and you saw the signs on the bridge, they all put "Puente Paso del Norte" even on the mexican side. Paso del Norte is the original name of Ciudad Juárez and it refers to some historical events, that's also the origin of the name of the city of El Paso, on the other side)
