The area is usually well taken care of. They close off an area every few weeks so they can fix it up. My dog loves that there is grass and that there is a lot of areas to smell and explore.
The people and dogs are nice. My chow chow does not care to interact with people and many of the other pet owners respect that. He will smell the other dogs and then walk away. If you forget your tennis ball, don't worry there are a lot lying around that you can use.
The only bad thing is that's owners sometimes do not pay attention to their dogs. Sometimes other dogs would jump on my dog and pull his tail or try to bite him. But other than those owners, this place is a great place to socialize your dog and interact with fellow dog owners.
