Peter Street Basin Cleanup

Another successful cleanup at Peter Street Basin! We had an amazing time cleaning up and exploring the area. Our team scooped trash out of the cabin water, scraped grass and mud, and went on ball rides to inspect the waters for pollution. The weather was perfect, and it was so nice to enjoy some community bonding time. Huge thanks to everyone who came out to support our basin cleanup initiative!

Check out this video with Alex V. going on an impressive balling session!
