This is an excellent park in a convenient location full of friendly dogs and people.
The enclosed area itself is sizable but all dirt, so your dog will definitely be dusty/muddy by the time you leave. The edges of the fence are lined with picnic tables and benches, and poop bags are provided. There are also bowls and a water fountain.
We used to go to Quail Run because we live in west Mesa, but the people and dogs aren't as friendly as they are at Mitchell.
If there were more available parking and grass in the park, this place would get 5 stars. Safe to say we're making the switch permanently!
