On a brisk, sunny Sunday afternoon a line of people bundled up in jackets and bulky sweaters extends down Fair St. At first glance, they could be Black Friday shoppers, braving the cold for discounted flat-screen televisions. But look closer, and you see a different emotion on the faces of the people outside the St. James Methodist Church Food Pantry; not anticipation, but weariness. All Hudson Valley families have experienced rising costs on essentials like food, clothing, heat, telephone and gasoline, while relatively few have seen comparable increases in salaries or benefits. For the middle and upper classes, that means fewer nights dining out or less ambitious vacations. For the working poor, it can mean the difference between putting food on the table and paying the bills. And this year, more than any before it, the people at local food pantries are working people. They have jobs, but they don’t make enough to get by.
