Thanks Guest2 for your accurate information from the news release on the actual location of the accident.  I  don't know why the RG is so vague on locations outside of the Eugene area,  as in this and today's Alma story. Events are too often defined just by their distance from Eugene or a larger city rather than specific geographic local.  
In this case, if it was at milepost 6  near  101, it  was around Coaledo, Green Acres  or Delmar, not  very far from Coos Bay, so a long response time would not be expected.
