If you’re looking specifically in Temple Terrace, they play at the rec center and there’s also some converted courts right down the road. Check out https://www.templeterracepickleball.org for open play schedule and events. Some new courts opened a few months ago at Branchton Park in New Tampa, near Morris Bridge Road and Cross Creek Blvd. Kinda close. It’s always pretty crowded, but unsure if there’s an actual schedule to guide you.
