tarbubble, your fear is not irrational there was a incident. just think the whole thing out, cougar attack will be one of the lowest risks you will face on your trip. the area i live in is filled with grizzly i feel alot of apprehension and fear every time i solo but i would not be able to stand myself if i just gave up and did not go.there is usually a couple incidents a year but there is also thousands of hours of bush use put in by workers and hikers.the odds are almost nil anything will happen. i push myself to go and the reward is tremendous and eventually you conquer your fears .the only way to is to go thru them .i would wear a large bear spray and a sturdy sheath knife on your person at all times ,stay alert trust your gut feelings go on your hike and keep going it is what makes us alive.
