 Dinger is the only pharmacist who lives in Wall. To take a sick day, she needs a fill-in from Rapid City, nearly an hour away. You know, to just cover my relief, but, you know, you take what you can get and try to schedule around it, and hopefully it all works out. Thank you. Thank you. Wall Drug is a lifeline for locals, whether they need routine medication or treatment for something more unusual. Dinger once gave antibiotics to a park ranger who was bitten by a prairie dog. You never know what kind of diseases they might be carrying.
