It's All Good Farm is a farm stand and petting zoo just outside of Antigo. It sounds like they have all your standard petting zoo animals, as well as opportunities to feed some of them. They have pony rides and supposedly COW rides! Plus, they have some really cool events; I am so disappointed I can't get to their Super ZOO Splash Weekend. They are setting up pools and slip'n'slides!
If you are in the area, be sure to check them out.
