Thanks to Allen for the photos. Along with flowers, someone has left a pictorial memorial at the Alki Statue of Liberty, which became a Seattle gathering place after the 9/11 attacks,
While hundreds gathered there for a 10th-anniversary vigil in 2011, nothing formal is planned today/tonight.
SIDE NOTE: On 9/11/2007, the refurbished statue was unveiled. The plaza surrounding it, with a new pedestal for the statue, was dedicated a year later.
