BY KATHY STEPHAN Let me introduce you to my friend Charlie. At 75, Charlie falls into the category of a senior food shelf client. He hasn’t been feeling up to par so he visited the VA clinic in Brainerd today. The VA had run out of the prescription he needed so he had to purchase it himself for $55. And, since you can’t drive to Brainerd for free, he estimates another $20 just for gas. That’s $75 of unplanned expenses for Charlie… on a fixed income.
