On really long road trips, say Eastern PA to South East Florida in, oh, 22 hours....... The family would sleep. Suburban, wife in right seat, 1 kid in row 2 and one kid in row 3. I would put on soft jazz on the "house stereo" and myself would wear a noise canceling headset with a CB and my tunes in it....... Hendrix, Floyd, Gomez...... you know , the stuff to keep you awake.....
