i'm a lousy shot, wouldn't look for arrowheads and used to drive an old willy's truck named "tater"with big, fat, low air tires on 40 acres of dunes owned by friends.   we stayed on the "road" as it were so as not to damage what little struggles to grow, but the 'road" was just a marked path in the dunes so it was like a tilt o wheel.  great fun - young and stupid.. all kinds of ways to die there...
