Fleeing from a preditor is a bad idea.
Bicycles aren’t ideal defensive devices.
A can of bear spray would have made a big difference.
I'm not sure bear spray would be effective against an ambush predator like a cougar. They don't usually charge like a bear or even an African lion. A person might see or hear a bear coming...not so much with a cougar I don't think. A person would pretty much have to have the spray container already in hand maybe? Have to be awful fast with it.
I think Mountain Lions are magnificent cats but I see a pattern. As their prey move out of the mountains into communities where they aren't hunted (even protected) and well fed on lawns and gardens, the cougars follow their prey. We are caught in between and become easy prey, too.
Even though these bikers were on a mountain trail, the cat was hunting for its favorite meal and hungry. The bikers were there and the deer were not.
Animal control needs to be more proactive in running the deer out of towns and back into the hills or this will happen more and more. (My two cents worth)
...and 2-legged predators....Watch the movie “Deliverance”, which highlights the dangers of swift water and local wildlife.
Here is the phrase from the article one should probably focus on:
“Authorities said this is the second cougar attack death in Washington state in the past 100 years.”
Now let’s look at how many bicyclists have been killed by drivers, drunk or not, during the same time span, and that should put things in perspective.
Cougar attacks are rare anyways, but an attack pressed home repeatedly against multiple adults is a freak event. Yes, in this situation a gun would have definitely saved them. I always carried when I rode my bike in earlier decades. But if you are prone to worry about cougar attacks, you’re not going to enjoy the Western outdoors.
A friend of mine in Eastern Oregon when he plants trees on his property, wears a pair of boxer shorts with a happy face on the back. When he is bent over, the face is guarding his six from any big cats stalking him.
