Early gift from my son

Last time my son visited from Chesapeake VA, we spent a small portion of the time off road on the dirt bikes. Anyway although you cannot get lost out here because of all the open land marks and distinguishing features, you can still get temporarily turned around on one of many intersecting mule trails that crisscross the desert to different abandoned silver mine locations. Anyway he called me yesterday and said "Dad I'm sending you a special early Christmas present cause you need it with all the time you spend out in the desert." So I received this GPS which hopefully will allow me to map out specific areas and direct routs.
