It's 86 degrees on a humid Saturday evening in June, and sitting in Rock Island's Lincoln Park, it's easy to reflect upon a gold and pink summer sun setting in the west. To the south, the lights have just clicked on the basketball courts as a neighborhood pick-up game is in full swing. To the north, a young couple push their giggling toddler on the swings of the playground. And to the east, the lights are dimming on the Italian-Renaissance-inspired structure enveloped in the arms of the giant oaks as another evening of theatre in the park is set to begin.
