Firstly, nice shots! And good job getting decent shots without bothering the moose. I like #1 and #4 the best (the wider angle views) because they give a great sense of place. So it goes to show that there's no big advantage in getting close. With regards to the grizzly gang, that sort of behaviour just makes me cringe but I know it happens all the time. Out here there is pretty good patrolling being done, and when a bear is hanging out near a road then parks personnel will be on site to police the crowds. That very thing happened to me two weeks ago when I was on my road bike (on a road that is presently closed to traffic) --- a park ranger told me there was a grizzly up ahead. Sure enough, I went past and there he was, 10 metres off the road in the grass. Needless to say I did not stop to grab a shot, and in fact I made a new PR on the Strava segment for that part!
