I've seen them jump a few times myself up on Sak. The first time I was about 15 and even though I knew what I saw I almost didn't believe it. Of course nobody in the boat believed me. Last year we were running west of Indian Hills and one came flying out of the water of to our side about 50 ft. Both me and my brother-in-law happened to be looking at the exact spot when it jumped so we saw the whole thing.
