FYI for Elliott Bay-watchers, and anybody visiting Alki, on Saturday – King County Water Taxi spokesperson Al Sanders tells us that the WT and the U.S. Coast Guard “will be holding their annual joint training exercise from 9:00 a.m. to 3:00 p.m. across Elliott Bay.

ADDED SATURDAY: The drill activity ranged outside the bay, too – Chris Frankovich sent this photo shortly after 3 pm:
