Autumn with a Touch of Winter

It is still autumn.  And a lot of the trees are hanging on to their leaves.  The city had scheduled leaf pick-up for this week.  They came, they swept, but they certainly didn't conquer.  Most of the leaves are still hanging up there.  I heard a teaser on TV about why, but I never heard the story itself.  Stubbornness? Wouldn't that make a great story?  -This just in.  The trees in Minneapolis are not losing their leaves in a timely manner this year. Experts have determined that the trees are just being stubborn.-  I would love to hear that. But since I didn't, here is a bit of the stubbornness of trees.
