We lived in Salem at the time and were outside washing our cars when it blew. Heard the boom and thought it was a sonic boom. I remember cleaning ash out of the gutter later on. It was quite the chore. Went to a Trans Am race in Portland about 3 weeks later and it was tough on everyone. Any time a car went off track big plumes of ash wafted over the track and the spectators. The cars were running max air filters as the ash was very abrasive.
