If you haven’t heard yet about the big Alki Beach cleanup that is part of International Coastal Cleanup Day this Saturday … go sign up! Sponsors including Puget Soundkeeper Alliance would like to know how many people to plan for. You can sign up outside Duke’s on Alki starting at 10 am Saturday – the cleanup runs till noon, followed by an afterparty till 2 – but they say early online signups are even better.
