I love the St. Louis Zoo. One, because it is free and two its nearby my home so i can just pop in when i want. If you have kids and you want to pay a few bucks you can ride the train around or visit the children's petting zoo. I love seeing the animals the most though. oh and you dont have to pay for parking. there is always parking on the streets somewhere!
Pros: free, not crowded, family fun
