Hi everyone,
Thanks for all the feedback. I have to say for wildlife viewing I haven't been anyplace that tops Yellowstone. Around every corner there seemed to be something amazing.. and we were there for two weeks so that is a lot of "amazing" 
Very nice. You seem to have mastered your new lens quickly. Where did you spot the grizzly?
The dark Grizzly (1st photo) was on the East Entrance road, the one on the hill was on Dunraven pass.
Nice pics. I just got back from YS yesterday, but I didn't get such good shots as you. I have a couple questions for you:
Were you hiking through trails to get some of these shots or were they from the side of the road?
Also, with a 400mm, it looks like you still had to get pretty close to in some of these shots. Did you get pretty close? Some of those bear shots seem too close for comfort for me. How were you able to do it? Did you have to camp out in the woods?
We were there for 2 weeks and did our share of hiking but honestly we saw more from the roads then we ever did hiking. The dark Grizzly was taken from ~30 yards, we saw that bear twice, the 1st time was with a Ranger present so we took our cues from him. The 2nd time we saw it we followed his suggestions for viewing. The one on the hill was actually taken from the car as we were in traffic because of people watching him. There was no safe place the park the car and no safe place to stand.
Like I mentioned, we were there for 2 weeks (flew into Bozeman) and took off for a few days to Grand Tetons, we drove ~1800 miles in total. I still can't believe the things we saw from the car and lookouts compared to the hiking we did.
Thanks
John
