Each month Switchback provides a prompt and we want you to send us your best work inspired by that prompt. The winning entry as decided by our editors will be featured on Switchback. Contest submissions can be poetry, fiction, nonfiction, or even art but must be 500 words or under. Please send us only one submission per prompt and only previously unpublished works. We accept simultaneous submissions but please notify us immediately of acceptance elsewhere. Make sure your name DOES NOT appear on the submission itself. The deadline for submissions is 5:00 pm on the last day of the month.

The March prompt is: "Three men walk into a bar."
