Yes, just about every one ha!  The key is to be prepared for the situation, but not let it stop you from getting out.  It really is a treat to observe these beautiful animals in the wild.  We've come up close and personal with a mountain lion feasting on a fresh kill, multiple bears foraging for berries and bugs, moose tending to their young, and giant humpback whales trying to knock us off our boards.  Kai was in my belly with our mountain lion encounter, and Stella in my belly for the humpback whale experience.  Aria on the other hand, came out roaring like a lion cub so she fits right in with our animal-loving family.
