This unplanned leg of our trip meant we navigated via whatever maps we could find : the atlas from the kind fellow on the ferry , the brochures at the drugstore , the ranger 's station maps , the free phone books at the Chamber of Commerce . Whenever we met a local , we asked for suggestions . And they never let us down .

Question: Why did the narrator approach to strangers ?
Answer: To get some drugs .To get info on the area .To get info on where to find phone books .None of the above choices .
