Unfortunate for the Gorilla, always hate preventable forced hand animal deaths.
Just this passed weekend on hwy 93 up the hill from Radium there's no stopping zones as a mother grizzly and her cubs are frequenting the area. Of course, there's half a dozen cars either stopped or slowly idling along the shoulder, even witnessed a car pull a u-turn on the hwy to get a better look. But worse was the 3 individuals who felt the need to exit their car and walk towards the bears, literally 8-10 feet away and toss some hotdogs their way.
I of course reported it to the parks phone line along with their rental car license plate, however it just goes to show you how little regard some people have and unfortunately its the animal's who get eradicated for human error.
