I don't understand your geography of groceries. If you are in a dense city where congestion means that 15 miles is a 90-minute trip, it is almost certainly true that there are hundreds of grocery stores in a 15-mile radius, right? Isn't the important thing your actual distance to a grocer, rather than the time needed to travel 15 miles?
