In case you never heard of Millie Bush, you're not alone. Apparently, she was President George H.W. Bush's dog and since this dog park is in George Bush Park I suppose the name of the dog park is fitting.
The dog park is pretty typical of all the other dog parks I've seen. I think they're all made from the same basic template in that they offer the same features - dog gates, dog wash stations, and lots of room for Fido to run and play.
Watch wear you step. ;)
