Why Did the Geese Cross the Road?

I was walking once in park.  The park had a road running through it that was a regular road used by motorist.  It wasn't the busiest road but it had a fair number of cars travel it.  While walking I noticed a group of geese on one side of the road.  Or a gaggle if you will.  Geese live in a group which makes them social but as this article explains their is flexibility for individuality as well.  I watched the geese eat grass on one side of the road.  Eventually one of the geese carefully crossed the road.  I suppose there was more grass on the other side of the road to graze on.  After the one goose successfully crossed the road another goose followed and also crossed the road.  Then two more crossed road.  More and more slowly waddled across the road until all of them had crossed.  All because the one took the chance and braved the road.  And then another was brave and decided to follow.  And then others decided to be brave and follow and so on.  Until all the geese had crossed the road to greener pastures so to speak.  That is a demonstration of leadership out of individuality.  One is brave and does something different based on their individual assessment, others then are brave and follow that individual based on their own assessment which then causes others to join in.  That is a lesson in leadership that has always stuck with me.  Does anyone else have any examples of leadership they would like to share?
