I like how the smart people on one section of dock run back when the whale turns around. Seriously. As Travis mentions, whale are quite dangerous.
I'm amazed when people are calm and comfortable when really, really close to these creatures. Even killer whales, which while not as big as a humpback, I think humans look like sea lions to killer whales and probably a similarly tasty morsel.
The footage ends rather suspiciously right as it rounds toward the person crouching at the end for a photo (and not running). Here's hoping all the dock bits and people survived intact!
And I don't want to experience either whale or dog fish farts, thank you for that painful idea, Dale!
