After 50-knot gusts and a wind-bound afternoon in The Dalles, Oregon, we had to make up for lost time today, traveling 270 river miles and transiting through 4 locks to our destination of Clarkston.  With no time for side-excursions, the day was dedicated to cruising, and expedition leader Sheri Bluestein craftily improvised a schedule to keep us entertained.  In addition to the thrill of passing through the locks, we saw presentations by our National Geographic photographer, Smithsonian historian, expedition geologist, and even our expedition chef!  The evening cheerfully concluded with beer tastings and trivia night.
