Oregon's "No Refusal Weekend" for July 4th?

This one's for the Americans. Are there any Oregon people here?

I'm aware of the implied-consent doctrine in many states regarding breathalyzers, but I'm wondering if any Oregon'ers have any views on this, and also wondering just what standard of evidence is required to get a blood-draw warrant in that state.
