Drunken Pen Writing has posted their Spring Open Submission Period call. They're looking for short stories up to 5000 words and flash stories up to 500 words. And they have topics for you - 1. Hillbillies, 2. Spring Time, 3. Magic. You must use one of these topics in your story. The deadline is June 1, 2018. This is a non-paying market. You can find the details here.
I know, I don't usually publish non-paying markets but this one sounded interesting.
