I wish the attack victims well.

I do not know if anything would work in the momma-and-cubs- situation, but in my imagination I would sure appreciate a thick fog of bear spray to increase chances of distraction to aid safe extraction.

Please educate my imagination so it more closely resembles reality. How does bear spray work? Do bears see through bear spray or can you use the spray to create a blank curtain-effect to hide behind? Are bears threatened by the spray so it makes them more aggressive?

Thanks.
