For folks planning rides including Hwy 30 and Willamette Blvd. as far south as Rosa Parks...Seattle to Portland is this weekend.
I think it concludes at Peninsula Park. One day riders Sat. then the two day riders rolling early to late Sun. Highway 30 North of the St. Johns bridge will be filled with riders heading south into Portland. Sauvie shootout folks will have company coming back to town. Also this weekend is the Cathedral Park Jazz Festival under St. Johns bridge. Auto traffic will probably be more intense as well.
