I have an idea!
A renga is when someone writes a haiku (5-7-5) then someone else writes two 7-syllable lines as a response to the haiku. Then the first person writes a haiku in response to those two lines and so on.
I'd like to try this here with you guys. I'll let someone else start if they want. If no one posts anything I'll put up a haiku and hope at least one other person plays along
