Costumed crusaders save the day! (Seriously)

Must read: Jeff Frantz's piece on two guys who dress up in superhero costumes, call themselves the Keystone Crusaders and go around Harrisburg -- a city more or less in freefall -- cleaning graffiti and dog crap, giving water to the homeless, helping out people who need help and doing whatever else urban despair-fighters might do.

A snippet:

They begin — as they have at least twice a week since March — in the Market Street tunnel. 
    
“Good Morning!” they bellow, warming up their superhero voices to the office workers walking west, and the residents heading east. 
    
How can anyone, Commonwealth asks, feel good about their city if their first sight of it is this cavern of filth? 
    
The battle is joined, and Commonwealth’s three utility belts/fanny packs, come open. 
    
A hand-held vacuum for cigarette butts. “L.A.’s Totally Awesome,” the Dollar Store industrial cleaner they don’t bother diluting. Spray paint bought on clearance. Their real superpower is bargain hunting. 
    
When danger arises, they reach for the original crime fighting tools. Broken glass is no match for Kevlar-lined gloves! No clogged gutter can withstand a steel baton!
