In the United States, the fourth Saturday in September is National Public Lands Day – a day of service and celebration for the stewardship of public lands, from community gardens to national parks. It’s a day to give back as well as a chance to visit any of the county’s national parks for free. If you’re in the US, consider visiting a park this Saturday or reflecting on how to steward nature and resources for tomorrow.

Let’s also celebrate the amazing LEGO Park Ranger account, celebrating 10 years of sharing daily builds inspired by America’s parks and history.

The LEGO Park Ranger account is run by Gavin, an employee of the Nation Park Service, and his wife, who started the account in 2015 to support a LEGO ideas project. Frequently drawing on pop culture, the builds are used to highlight specific parks or historical events. You can read an interview with Gavin about the initiative here.
