Dang, I took some kayak classes from Dan about 17 years ago. He was a great instructor. One thing he did was have us learn to hand roll before we could even tough a paddle. I don't know if that's the standard now, but it was pretty out-of-the-box instruction around here.
He must be a great SUP instructor too! Maybe he'll visit Missoula again some day, I'd love to give that a shot! Pipeline on the Lochsa would be SWEET.
