Is That Why We Don't Get Visitors?

Tonight we heard coyotes in the vicinity of our backyard.  They were cackling their strange song, so Ryan went outside to scare them off.  I stayed inside with the kids and watched from our dining room window.

Caleb was quite upset about his dad being out there with coyotes.  He didn't cry, but was close.  Isabel reassured him that Dad would be ok.  She said "Dad will be ok 'cuz he smells bad".

Apparently Ryan doesn't smell so appealing to wild coyotes.  It must be a scent undetectable to the human nose.  Or maybe we all smell bad and no one is telling us?
