You have a road map for the area surrounding your present location; however, because the map was produced by the Super-Duper gas-station chain, it shows only the roads in a 30-mile circle, the north and east directions, the locations of two Super-Duper gas stations, and your present location. Actually, you want to go to San Diego, which you know to be 400 miles to the south. How might you get there, if you know how to drive, have a car, and sufficient money for gas, food, and lodging along the way?
