Last year I went to Canadian Rockies, saw five black bears. no grizzly bear.
Black bear usually is ok, Grizzly bear is more aggressive. but anyway, I know we should not be too close to them, so a good telescope is a must buy.
I plan to go at this time and setup a study group at my blog. A lof of people plan to go, I guess every year summer time Alaska is a big vacation destination.
