A close friend of mine taught me this neat trick with any smart phone that can drop “pins”. We used this trick with an iPhone in the maps app. You can pull up the map of where you currently are parking and tap the screen in the bottom corner. The screen will allow you to select the drop pin button. This will drop a pin at your location that can be retraced when you leave the building. This would be great after a sporting event, shopping at the mall, or for students that work at large complexes.
