You could call it SXSW for environmentalists, except it's originator wants it to be for everyone.
Not only is he an environmentalist and a nationally-known builder, but Dallas' Trammell S. Crow is a Republican and the founder of Earth Day Texas, which is likely why the Lone Star version of Earth Day is a decidedly bipartisan celebration.
It's one last Earth Day Texas this Friday, Saturday and Sunday in Dallas, but not because future events are being called off -- in fact it's increasingly popular -- but because they're changing the name.
Organizers say they're planning a more national approach for the 2018 celebration, and they want to call it "EARTHx" because they expect the event -- which drew 130,669 people last year -- to be even larger next year.
And the Fair Park gathering is already reputed to be the largest Earth Day on Earth.
The now-three-day-long, largely free celebration begins Friday, with new and educational kid-friendly attractions.
It's been growing since Crow started it in 2011.
Some people consider Earth Day to be the province of "treehugging" liberals, but the event (which was first celebrated in 1970) as observed in the Lone Star State features attractions as diverse as a speech by Republican former Governor (now Energy Secretary) Rick Perry and readings on eco-subjects by New York City poets.
If that's not interesting enough, US Army General, Retired, Wesley Clark is expected to appear, as is National Geographic's famed marine biologist and lecturer Sylvia Earle.
Also new this year is the E-Capital Summit, bringing together clean energy startups and investors.
Only in Texas.
Only in Dallas, really.
