Thursday Photo Challenge: Round

The theme for this week is ROUND.  I was surprised how many of my photographs fit this theme.  Here are a few of my favorites.

This photograph was taken while sitting in traffic.  As a
preschool teacher, I always keep my eye open for unique
images that I can share with the children. 

This is an image I also captured while sitting in traffic.
It was taken at the site of the O'Hare Airport Expansion.
