The interesting discussions relating to bussing, pelotons and human/animal 
behavior call to mind some papers I published at Caltech in 1969 relating to 
the advantages of Vee formation flight for migrating birds.  Because the saving 
is in induced drag the least energy position is, counter intuitively,  the apex 
(point) of the Vee.  I was immediately assailed by ornithologists and bird 
watchers, who knew much more about the subject than I, and rather than checking 
the equations, challenged my results on their ideas of behavioral grounds.  It 
turns out that the apex position is indeed taken by the oldest and strongest 
bird.  Would he, they asked, take the easiest job?  My answer was:"yes."!
