You all are excellent. I might end up using all of them.
I *really* got a kick out of the top of the food chain one.
At one point we were slowly walking our boat downstream while the bear was fishing on the next bend. The bear knew we were moving his way but he wasn't very interested in giving up his fishing spot. The guide was holding the boat while he and I waded down toward the bear (I was taking photos) and my wife sat in the boat. So the bear was chasing after a salmon and ended up coming toward us (not in a threatening way).
That was the point at which my wife said, "Uhhhh, we're close ENOUGH now, aren't we?".
As a human, you don't feel very much like the top of the food chain when a critter that big and with that many pointy ends is pretty close to you.
We saw that bear off and on for three days. Our guide nicknamed him "Digger" because of a cool thing those bears do when there's many, many salmon around. Supposedly a bear that big might eat two hundred pounds of salmon per day (or more!). Their bellies get so distended from all that food that they can't lie down and sleep comfortably. So, they dig a big hole on a sand bar and lie down to sleep with their belly hanging in the hole.
Here's a photo of my wife pretending to nap in one of Digger's holes:
That's a really big hole for just your stomach.
Here's what he was eating:
Here's what that salmon would look like if he had been in the river for a couple more days:
Here's a long-distance shot of that bear standing up to look for more fish:
And here's what he looks like when he's in hot pursuit:
