To be honest I have only taken Maximus to gateway Park...which as the beach....grass and a childresn palyground....and a park on Victory Blvd...that I can't think of the name which is shaped almost like a ovel and has a pond in the middle and the ducks are there plu there is a carpusel...but Maximus chases the poopr ducks and they finally figured out that they outnumber him and came chasing him back this weekend
