Once in a Blue Moon

Image taken from my deck near Gary, South Dakota on August 20, 2013.

The next blue moon will be in 2015.

A blue moon is an extra full moon that appears in a subdivision of a year, either a fourth full moon in a season or, recently, a second full moon in a month of the common calendar. Metaphorically, a “blue moon” is a rare event, as in the expression “Once in a blue moon.”  ~ Wikipedia
