April Vokey should be familiar to blog readers, as we have featured her several times already (here, here, and here, for instance.) Above is a video of April giving a presentation on the double haul at a German fly-fishing fair. She has some trouble with audience participation, but the casting instruction is spot on. She discusses some of the most common errors she sees, and then she even gets into a few advanced hauling techniques. One does have to quibble with her characterization of Americans, though.
