Colorado Parks and Wildlife officials say that if a coyote approaches you:
Do not run or turn your back.
Be as big and loud as possible.
Wave your arms and throw objects.
Face the coyote and back away slowly.
If attacked, fight back.
Fight back? Anyone who needs to be told this is probably dead meat walking. Hell yes, "fight back"! And have something with you to use to fight back. Several somethings. Lately I've augmented my carry piece with a tomahawk of which I am growing inordinately fond. Doesn't weigh much and it's only a "camping tool" if anyone asks.
That might not go down real well in the 'burbs but out here in the sticks it's just fine. This isn't Ponyland or Friendship Garden, and those rustling sounds aren't unicorns.
Your tomahawk sounds like a winner to me along with your carry, especially in a case like this with more than one attacker.
