My two very close friends were bow hunting Elk last year in the Hudson's Hope area(B.C.), and bugled in 5 adult grizzlys. The bears came crashing in from 3 different directions. The guys were sitting on their tree stands at ground height - of course, it is illegal to pack handguns in Canada & it is illegal to shoot large big game with a shotgun and slugs(although effective close up). It was tense for along time with one of the bears inside 8 feet of big Dave, alomst a bear himself at around 300lbs. and 6'1". They winded Len, who was screeened by some brush, about 20 feet away, and crashed off into the bush. The bears are BAD in that area and also deem rifle shots as dinner bells.
: As they were just out on a hunting trip at this time - I'll have to check to see if they were the ones attacked this year.
