We have several roadside zoos in WI. I think the Milwaukee zoo is the closest to being a decent zoo around. The large zoo closest to us has recently within the past 20 years been updated from a roadside zoo. The enclosures are still way too small. Also, our zoos don't have decent indoor enclosures. For the Wisconsin climate they need much better winter enclosures for the animals that can't take the cold. Imagine a poor lion being put in a small kennel run indoors for 6 months out of the year. -By roadside zoo I mean they have cages like 6x6 dog kennel runs set up in a circle for people to walk around and see. Sometimes tha animal can barely move. There are no regulations in WI, you just need a permit to own the animal.
