The edge of a Lily pad

I love to see the tiny bubbles and patterns that form around the edge of a Water Lily leaf/pad. This photo was taken in the ENMAX Conservatory at the Calgary Zoo on 6 October 2015.

The west entrance to the Zoo will be closed from 13 October till April 2016, so I did want to get in another visit before then. I don't like the drive home on Deerfoot Trail from the north entrance, so tend not to go to the Zoo all winter. "Calgary's infamous freeway (Deerfoot Trail) has taken the dubious top spot when it comes to this city's most dangerous place to drive." From the Calgary Sun newspaper.
