speaking of chicago, on my bike trip cross country, we were riding late at night to get to a messenger mud wrestling party to benefit a womens shelter, when we were lost and riding downtown we came to wooden DO NOT CROSS barricades that really only served the purpose of blocking cars... we just kept going... then we passed some kids with flashlights and they were too busy yacking to notice us approaching and started shouting at us to get back, then we just took another corner, and there was all this movie filming going on and it turns out we rode through the Batman set lol...
