… sculpture, by Robert Glen
It took the artist 8 years to complete this installation, and there is a Horses of Las Colinas museum nearby that documents the process.

I’ve been there. The pictures don’t do them justice because of the scale.
So energetic
One of my favorite places to stop when driving I-90 across Washington. The setting is pretty spectacular.

Thanks for the link. That’s an incredible art installation and I’m going to feature it in the near future.
