Today's aerobic exercise

I shared this from my FaceBook post from today.
My run for today was aerobic, to say the least. My heart is still pounding. I was running with my dog in the South Valley Open Space park. There were lots of cars in the lot so I figured there would be lots of people and we would be safe. We had been menaced by a big coyote 3-4 weeks ago. After the turnaround, my dog started looking behind her and pulling hard. I turned to see that big coyote running at us, only 20 yards away. Do you know how aerobic it is to walk backwards fast for 1/2 mile pulling a 75 pound dog with one hand, and alternately blowing a whistle, and screaming and waving my other arm while a howling growling coyote as big as my dog follows only 10 yards away? Luckily a teenager ran around the corner and we joined her....safety in numbers...and the coyote slunk back into the scrub oaks and tall grass. I did notify a ranger so they can at least put up warning signs for other dog-owners. Thus ends my solo trail-runs for the year. And my dog was on-leash and we were on marked trail.
