Green Day.

Scenes From Sunday's Seventh Annual Oak Cliff Earth Day.

Hundreds of kids, young adults, parents, grandparents and — yes, of course — tons of pet dogs on leashes (some even with sunglasses) gathered at Lake Cliff Park in Oak Cliff for the seventh annual Oak Cliff Earth Day festivities on Sunday. And, hey, that was cool.

Far cooler, though: The number of other animals in the park. It was kind of amazing. There were wild and tame ones alike, and kids were able to not only enjoy the usual petting zoo far, but see a lemur in action while learning about preserving wildlife. Hell, there was even a showcase of live bees, and a station for kids to learn about local honey manufacturing.

It wasn't all animals all the time, though. Attendees also learned bits about recycling and re-purposing materials, too. And the uprising of urban farming was a particularly popular topic throughout the event.

But let's be clear: Though the event was highly educational, it was also fun. There was live music, a humorous Elvis impersonation performance and a climbing wall to boot. People also seemed to just be enjoying being outside, sitting by the pond and setting out in the sun.

All in all, it seemed to be a good day for Oak Cliff and its thriving local business community. The local vendors did an outstanding job of communicating the importance of green living, and people were definitely paying attention.

Most participants likely walked away from the event with a little more knowledge about living green like where to buy local foods (or grow their own), where and how to recycle the impossible (like chemicals and electronics), and how to accomplish composting even in the most urban of environments.

It was cool, you guys. Sometimes, Earth is pretty awesome.
