How do I know summer is right around the corner?

-It's getting freakin' hot and humid!

-FIRE ANTS! Blech!
-Beautiful moths in my garden!
-Flowers!
-My first eggplant of the year! It's still tiny but isn't it gorgeous?
-And the number one reason I know it's almost summer... tomatoes, people, it's all about the tomatoes! And yes, I will be eating these little beauties tonight!
