Just got this email from Sound Transit:
Northline 1700 (departed KSS at 4:05) is being held due to the report of a suspicious package near Galer Street. The Seattle Police Department has been called and we are waiting for their determination. This may also cause a delay in the departure of train 1702 (4:33 Seattle Departure).
It’s my sincerest hope that this is just some stupid mix-up and not something heinous. Of course, it’s quite likely that this is someone’s idea of funny.
