Bill and Nancy Wayte own Grant Street Grocery, the last neighborhood grocery store in Casper. In its heyday, Casper had 99 neighborhood grocery stores. The Waytes sell high-quality goods, donate to local nonprofit groups and help distribute locally grown produce. But all their efforts may not be enough to keep the store’s doors open. Small, locally owned stores often have higher inventory and per-customer operating costs, and face intense competitive pressures from billion-dollar corporate chain stores.
