From the city website:
Our City Park has lots of open space to enjoy! The South End is available for reservations which is perfect for your family or business gathering. It includes a pavilion with picnic benches and a huge charcoal BBQ & griddle. This is only where the fun begins as the entire City Park has lots of open lawn space, a softball diamond, volleyball, tennis and basketball courts, state of the art skateboard park as well as a playground.
