I heard it was not happening this year. Facebook says:
If you noticed today we effectively cancelled the event. We've moved the event to a german bier house in Tacoma with street parking. Last year between the Seattle Seahawks, rain and lack of attendance we barely made it thru the day and felt like we weren't giving what people deserved. This isn't the end for Oktobugfest, it's a turning point for us as organizers. In 2018 this event will not be in October and will be a summer event out on the grass in a very wide open park on the eastside. We'll always stay the same, crusty, rusty & patina with stories of fun and how it used to be. We'll see most of you Sept 24th at Fall Fling at Triple XXX Burgers where we'll have a booth selling warm hoodies for fall -mike
