Widowhood came late in life to Ina and Helene, two sisters living in Chicago. Now there is nothing holding them back from one last great adventure: a long, leisurely drive to visit family in Los Angeles. Only Helene knows how to operate an automobile, however, and she has been blind for years. But with caustic, beer-swigging Ina as her eyes, she's willing to get behind the wheel once again. And now, on sparsely traveled back roads in the dead of night-cruising at a comfortable twelve miles per hour-they're off to see an America they never knew.
