Was just reading that this is the first time a waterway choke point (other than canals which are man made) has had a toll. The implications are intriguing for their novelty and unknown second order effects.

Also, the comment about the globe reminds me of a quip from The Daily Show that went something like "... something something War, or how Americans learn geography." You are lucky to have prior generations which provide such inter-generational teaching moments.
