Kelly and I took advantage of this rare visit to Navy Pier to do some people and place watching. The pier is apparently the biggest tourist attraction in the state of Illinois. Which is odd, given that it is essentially an airport without the security and the reason to be there. Long empty hallways swell into food courts and Chicago-themed tchotchke shops. Kelly, my wife, observed this, and suddenly the whole place made sense. I love airports and always have, so I was delighted. Particularly it felt like the international terminal at a second string airport. The plethora of families and couples, age ranges and nationalities, especially after the much more homogenous crowd at EXPO, was inspiring and touching.
