But barring the invention of a working crystal ball, the best nonprofits can do is put new donors to the test before their interest in the cause wanes. At least that’s the strategy that works for Maryland Food Bank, an America’s Second Harvest (recently renamed Feeding America) affiliate that distributes food to more than 1,000 shelters, soup kitchens, pantries and other charitable organizations aross the state of Maryland.
