Around the corner from the hotel we stayed at in Las Colinas was the largest Equine sculpture in the world, The Mustangs of Las Colinas. I found it by accident driving back to the hotel from running to the post office, and am so glad I came across it. Here is more info on the sculpture from the Irving Convention and Visitors Bureau.
When you knew where to look, you could sorta see the horses through the glass of the building you see in the picture behind the horses. The building you see in the background between the two buildings is where the Women's Retreat took place.
