Answer: Astoria, Oregon is just across from Washington state on the Columbia River. The Highway 101 bridge connects Washington to Astoria, and it takes mere minutes to cross. Unlike Washington, Oregon has no state sales tax, so many Washingtonians who live near the border shop there, and their cars would be seen. Also, there are several vintage paddlewheel river boats belonging to a river cruise company based in Astoria. From a distance, they are a similar size, shape, and white color as a Puget Sound ferry. That is probably what you saw cruising on the Columbia River.
