Tomorrow’s the last day of the year for the Elliott Bay Water Taxi — but if the forecast holds, today may be the last chance to ride it in dry weather. Friday’s bound to be fun no matter what, with free coffee and donuts promised between 6:30 and 9:30 am in honor of the final morning commute (as reported here last week, along with information on two ways to show your support for the Water Taxi and its new parent agency, the King County Ferry District).
