Mark is working with a realtor to find a location for the toy store he plans to open in his town. He is looking for a place that is either in, or not too far from, the center of town and one that would attract the right kind of foot traffic. Which of the following locations should Mark's realtor call to his attention?

• a storefront in a new high-rise building near the train station in the center of town whose occupants are mainly young, childless professionals who use the train to commute to their offices each day.
• a little shop three blocks away from the town's main street, located across the street from an elementary school and next door to an ice cream store
• a stand-alone storefront on a quiet residential street ten blocks away from the town's center
• a storefront in a small strip mall located on the outskirts of town that is also occupied by a pharmacy and a dry cleaner
