Good thing they’re not gathering at the school — since as we first reported last week, the renovations are ramping up, and the campus is closed for two years. But they’re partying just the same – all former Chief Sealth High School students from the ’60s and ’70s are invited to a gathering at West Seattle Golf Course tonight. The Class of ’73 is sponsoring it in honor of its 35th anniversary, but they want to share memories with those who came before and after. They describe it as “a free, casual event with a no-host bar and food available from the Cafe. Get-together starts at 5 pm, with music of the era until 10:30. Bring any Sealth yearbooks and memories along. No RSVP needed!”
