I guess that's not a horrible thing.

But for soccer, kids need futsal courts and indoor and public spaces for pickup soccer.

As they get older they do more regimented training at a club typically.

But there are a few big "sports complexes" with a lot of soccer fields, they're just a hike to get to.
