Columbia River Bar
Unless you have some masochistic need for punishment don't even consider crossing the bar. Other than salt water the only things out there are large waves and strong currents. Take the advice for the Salish Sea (Puget Sound) and enjoy! I've lived my entire life on the Columbia River and a friend crossed the bar in a Catalina 25 suffering severe damage including a stove in main hatch. However, his worst loss was a wife who will never go near the boat again!
