Fifth Challenge: Into Summer

10:20 PM 

 This picture shows how light it was on Saturday at 10:20 pm! It is strange to me that the first official day of summer is the longest day of the year. I wish the days stayed so long for a while, but just when summer arrives, the days already start to get shorter, reminding me that this season too is temporary and autumn will come before I know it. 

What is it for you that signals the end of spring and the beginning of summer?
