Currently, one in six Idahoans live lives that are considered food insecure. With Thanksgiving just a few days away, many Idahoans are planning their holiday meal. But there are tens of thousands of Idahoans whose biggest concern is not that big feast, but simply where they will get their next meal. Many turn to their local food pantries and they in turn go to the Idaho food bank. But food bank managers say this year the shelves are looking bare. Karen Vauk says they really are dependent up on the generosity of the community.    Every month, the Idaho Foodbank sets a goal to serve 1,000,000 pounds of food through its food pantry network.
