I have only one reference on a hillclimb in Seaside, Oregon. The article mentions that the Cascade Sports Car Club of Portland, Oregon was to be the sponsoring club. They were partnering with the Seaside Boosters.

Date of the event was to be Oct 16 and 17, 1965. The road used was the Lewis and Clark Road. Below is the only information I could find. Did it happen? Help me find info.
