I found information at Garfield's website about their candidate forum. It is just for School Board candidates so that will make it very focused.
Tuesday, September 29th from 7:00 - School Board Candidate Forum (doors open at 6:30 so I assume you could talk to the candidates before).
It's in the Garfield High Commons. Parking lot and building entrance are located at 400 23rd Avenue.
Moderated by KUOW's Phyllis Fletcher. Phyllis is a seasoned education reporter so I will be interested to see what she asks.
