Fields are a tough issue right now in Seattle.
Essentially, there aren't enough of them. During the winter, we need to stay off the big Seattle fields like Dahl, Magnuson and Sand Point, so that these fields are back in shape by springtime. We have an ongoing dialogue with Seattle Parks and Recreation, so they will tell us if we should be keeping off some area. DiscNW has recently begun renting sand fields in the winter for pickup. This information is usually found on the website as well.
