PRB+ Magazine is “the publication of choice for parks, recreation, and camp professionals.” They’re looking for stories:

“CALL FOR STORIES -- It's not even Memorial Day yet, but we're hard at work on our October issue!

Our most urgent need: long-form stories (up to 2500 words) about sustainability for our bimonthly supplement.

Other needs: stories about stadiums, outdoor facilities, and surfacing. If you have a bold new project in the works, tell us about it.”

They offer $400 for 1,200 words. Their per-issue freelance budget is small; most of the stories are submitted by professionals in the field. Read their post here, submit your materials here, and view fuller issue details here.
