Nothing like a good recap from Ian:

"Day 34 started off great! We worked our way right through lock 17 right before a tugboat with 15 barges was to enter from down river. A few moments later, the wind picked up to 20+ mph. Had to stop after 15 miles of paddling, ending up in Keithsburg, Illinois

Right before getting off the river, a tugboat flew by us, and for the first time, We almost flipped as a wave breached the canoe! Now enjoying a beautiful sunset."
