(Hamilton)---Your chance to make a difference in the battle against hunger takes place this weekend. The National Association of Letter Carriers will hold their 25th annual Stamp Out Hunger Food Drive on Saturday. All you need to do is leave a bag of non-perishable food items by your mail box Saturday morning, and your letter carrier will pick it up while delivering the mail. All donations made in Butler County will go to help the Shared Harvest Food Bank in Fairfield.
