Vivian Gray spent a lot of time thinking about ways to improve her yard. To hide cracks in the front walkway, she installed a path of cobalt blue carpet.

"I emphasize to my young people, it doesn’t matter where you’re at: Take pride," the 55-year-old said on a balmy Monday in May, explaining that just because she and many of her neighbors were considered "low-income," it didn’t mean they didn’t care about creating a safe and welcoming environment.
