🌿 Ocean First Has a Swing! 🌊🌳

Big news, Ocean First family! We are officially the proud parents of the Ocean First Swing at Thorne Nature Experience’s Lafayette Nature Center 🎉

For those who don’t know, Thorne Nature Experience is an incredible nonprofit that connects kids with nature through youth programs, summer camps, and Boulder’s first Nature Preschool. They focus on serving underrepresented students in Lafayette and Louisville, making the outdoors more accessible for all.

Our deep connection to Thorne runs strong—we’ve supported their mission for years, including a major donation in honor of Ocean First to help build the Lafayette Nature Center. And now, a little piece of Ocean First lives on in the form of a beautiful swing in the park! 🌳💙

If you’re in the area, stop by, check out this sweet spot, and maybe take a moment to swing into nature. 🌞✨

🧜‍♀️ BREAKING NEWS 🐙
In a shocking turn of events, a newlywed woman has been confirmed to be a mermaid after finally regaining her voice post-wedding. Local sources say she was spotted swimming off the coast in full tail, belting out sea shanties and Beyoncé. 🎤✨

Meanwhile, in unrelated-but-equally-mysterious news, a charter boat reportedly crashed into what eyewitnesses describe as a “giant squid lady with purple hair.” No injuries, just mild confusion and some awkward selfies. 📸🚤

Stay tuned for updates as our marine biology team investigates these deeply fishy developments.
