Thanks searcher99. I did some more digging in the forum and read this:

But, yes, if your ticket had been filed with any King County District Court, you could have filed your response at ANY King County Courthouse.


I’d have to drive to Seattle to file with prosecutor and would be easier if I could file copy in Issaquah king co. District. Is this still possible and is there any risk or downside to that approach (there systems aren’t linked, etc)?
