You should post that picture.
A quick back story...this bear had been hanging in this area of Yellowstone feeding on an elk carcass that had been killed by wolves. After the wolves were kicked off, he took over. He was kind of grumpy and didn't like all of the attention he was getting so he moved the carcass across the river (creek) and continued feeding over the course of about 3 days.
On the day we were here a BIG group of tourists began to form and with each successive wave, the new ones would move closer to the bear than the last group. Kind of a leap frog effect. The last group got to within about 60 feet of the bear on the carcass with the small river between them. At one point parents were sending their little kids (3-6 years old) running back to the cars in the parking lot with instructions to "go get daddy, he needs to see this".
There were several photographers there and we were all telling the people that they were getting too close. Several people gave us dirty looks and one person even said "mind your own business, he isn't going to do anything". After about 1/2 hour the bear got up and walked down to the river and put his head down like he was going to take a drink. At this point he was about 25 feet from the group of 20+ people on the bank. Being close to wildlife is all about learning to read their body language and his was saying back up and leave me alone. As a group, the photographers (us) were even farther back then the tourists all backed up as a group, giving this guy plenty of room as he was asking for.
I was one of the first to set my tripod back up and as I turned he jumped off of the bank and into the river in one big jump. He did this with a loud roar and popping his teeth. He was so close he sprayed the closest people with water. Once in the water he swung his head and swatted the water. He was pissed! At the jump the group began to scream, scatter and run and luckily someone in the group had the good sense to tell everyone to stand still (remember, only food runs). Luckily he then turned around went back to his carcass, figuring he'd made his point.
Unfortunately I had a 600mm lens on and only was able to get the bear. I wished I had a shorter lens that could have gotten the group in it too as they were just out of the frame to the front of the bear. At one point as we were all walking back to the car the lady who sent her little kid back for "daddy" made the comment..."how could they let an animal like that out here. He could have hurt somebody". Really lady?
Anyway not the greatest picture in the world but a great experience and a good story.
