@nayr69sg Your back yard fields are very well maintain. It looks like you can play football on it. Is it maintain by your local "town council"?
It is a multi purpose field. There are soccer posts but no net. There are soccer clinics for kids there in late afternoons. They split the field into smaller pitches and bring their own soccer goals. I have one myself.
Also the baseball diamond.
Maintained by the city of calgary.
Some of the walkways behind houses are maintained by the home owners.
I have such a space at my own house. See the green space beyond my back fence? We maintain it ourselves with the neighbors.
