1. An apparatus for automatically determining and storing a series of geographic locations, the apparatus comprising:

  • a GPS receiver for automatically locking onto and receiving signals from a plurality of orbiting satellites and, based thereon, determining a geographic location of the apparatus with respect to the orbiting satellites;

    an antenna connected to the GPS receiver for facilitating reception of the signals used by the GPS receiver to determine the geographic location;

    a battery for providing power, wherein the battery has a limited power capacity;

    a timer for measuring a preestablished time interval during which time the apparatus is in a power-conservation mode, and at the expiration of which the GPS receiver automatically determines a current geographic location of the apparatus, wherein the preestablished time interval is repeatedly measured and the current geographic location is repeatedly determined so as to result in the series of geographic locations corresponding to a movement of the apparatus over time;

    a memory for storing the current geographic location with the series of geographic locations; and

    a display for communicating the series of geographic locations stored in the memory, wherein when the apparatus is in the power-conservation the display is automatically turned off in order to conserve the limited power capacity of the battery.
