Henry Vilas Zoo is always improving. I was super happy to visit on a recent trip home to Wisconsin. Some of my favorite animals weren't available for peeking at due to ANOTHER new project by the zoo. When I was a child, this place was sweet, but outdated. These days, it doesn't let its size of free status keep it from being a cutting-edge, animal-based zoo. The environments keep improving, the animals look happy and healthy and everyone leaves with a smile!
