Offleash Parks in Seattle are so so so so  "sad face".

If I want to take my pup to a decent offleash park, I cross the border to Vancouver. 

I always think offleash parks in Melbourne are superb, 

BUT, a big BUT,

Regent Park offleash areas are way more superb than superb!

Extremely well maintained grass fields, with tall trees dotted across the fields, providing shades in the warm days.  "Free Roam" is not exaggerating at all
