Well PikesPeakCharlie, it happened to me. We had a sow and cub terrorizing the neighborhood dumpsters, so they said harass them and they'll learn they're not welcome. So I went into action, sleeping in the truck bed at nights til finally I got a chance. I chased them all over the neighborhood before sunup and finally, they went down in some bushes. I saw her stand up, then drop down. I heard those teeth chattering, and huffing and puffing, and here she came. I've been up against some scary things before, guns, knives, crazy people, but this ranks right up at the top. It was like a freight train. I stood my ground and she put on the brakes about 10 feet from me. Then the most amazing thing I've seen, she spun, leaped in the air, and landed on a tree trunk about 8 feet up. I conceded the field.
