I thought this was true in Wisconsin dells, but this place really beats all.

City museum, Saint Louis, Missouri. Sounds like another boring museum, right? No way! This is a 12 story indoor and outdoor playspace. It has tunnels, slides (10 stories!), indoor tree houses, school buses hanging off the roof, a rooftop Ferris wheel, and so much more. We could have stayed for days. If we lived here, I would. They make a point of saying it’s ok to get lost, and it’s expected that kids will, too. 

   
    
    

 
   
   
   
 Then we said a final goodbye downtown. The fountains in Saint Louis are open for playing in. So we did.
