On the river, I find it very important to manage expectations. People need to understand that they are going to face the rapids and flipping is a likely occurrence during the learning process. They might be afraid, nervous, excited, and exhausted, all at the same time. There's a million things they need to remember - good posture, loose hips, steady strokes, torso rotation, watch the current, edge the boat, look downstream, follow my signals - while trying to stay upright.
It's good to be back, if only for a little while.
