Los Angeles may be known for its celebrities, glitz and glam, but the city's mayor, Eric Garcetti, is focused on something decidedly less flashy: infrastructure.
Take the city's airport LAX, for example. You'd be forgiven for mistaking its terminals for a cramped bus station. And stepping out onto the curb can feel like an assault on the senses, with the horns, aggressive shuttle drivers and travelers jostling for taxis.
During New York City's mayoral race last year, then-candidate Bill de Blasio promised to fix big-picture problems, like income inequality and universal pre-K.
So he raised some collective eyebrows when he announced what one of his first initiatives as mayor would be:

Inside one in a series of abandoned homes along a blighted block of Detroit's Brightmoor neighborhood, filmmaker Tom McPhee walks through the remnants of a life — broken furniture, scattered knickknacks and a flooded basement.
"This is fresh water that's coming into the basement here," McPhee points out. "All of that plumbing has been ripped away 'cause someone found a value in it, so they don't care that it's running. This is all over the city."
