“Summertime is always the best of what might be” is a summer saying that has been printed on many images.
   
“Summertime is always the best of what might be. No one plans on dying in summer, everything is fresh and green and the girls swing by in clouds of perfume. Summer denies death, just as fall slowly erodes human hope” was printed in the book Dreamland:  The Way Out of Juarez (2010) by Charles Bowden (1945-2014).
