Last week I went to Genesse Off Leash Park in Seattle and it was the first time I saw pooper scoppers for dog owners to use instead of using plastic bags. I am not sure if many parks do, I know Marymoor does not. Great idea! I liked the park. It is not very big, more like a neighborhood one which is cool There's a water spigot, lots of pooper scoppers. The OLA has plenty of trashcans and a few garden plastic chairs to enjoy beautiful days with sun like the ones we have had in the last couple of weeks in Seattle.
