Try the tracking skills of you local Boy Scout Troop.
Just pick a location, save a message on the wall, and email or text to get the Trackers on the road.
An interesting feature is that any Tracker can invite others to join the chase. They can then join by referral of that Tracker.
Note that GPS is accurate to within 30 feet – so distances used must be fairly large. So driving around to the target location is permissible - but make sure that you pull over to operate any screen input. Use sounds to indicate progress while driving. It is recommended that a passenger or “buddy” work with the driver. All applicable cell phone usage laws must be followed.
Continued use of GPS running in the background can dramatically decrease battery life.
