Due to his busy radio schedule,
  he was hard pressed to find ways
  to get from job to job in busy New
  York City traffic. In an interview
  conducted in his later years,
  Welles tells how he "discovered
  that there was no law in New York 
  that you had to be sick to travel 
  in an ambulance." Therefore, he
  took to hiring ambulances to take 
  him, sirens blazing, through the
  crowded streets to get to various
  buildings.
