Someone to look up to

Standing on a street corner in an American grid city, you can turn four ways and see sky all the way to the horizon, shown by avenues like cupped hands. Into the blue - this is where you find your superheroes.

Standing on a street corner in London, you can see about as far as the next block. Less avenues, more walls. Less sky, more shadows. No one looks up, and space above the city is less for the heroes than for the homeless.
