Everybody used to walk, she said, carrying their groceries home from the market, taking the bus everywhere. For the last couple of weeks, the group has a new focus — trying to get shoppers to walk to the grocery store, not drive. The group figured that if people had carts to roll their groceries home, there’d be one less excuse to jump in the car. Through Thursday, the group sold 21 carts, partially because the group made the deal available only to people living within about a quarter-mile west of the store. Starting next week, the group will offer the deal to people living within a half-mile radius. There have been times she’s walked to the store before, she said, and found she had too many bags to carry home, so she’d call her husband to come pick her up. Living in the city has its great moments, the overheard conversations that stick in your mind, and the memorable scenes on the street.
