So, the REST of the story is that after saving Sofi and me from the rattler, my husband became a 12-year-old boy and, in an effort to get it farther from the trail, POKED IT WITH A STICK! If you'll notice there's a large 'something' in the snake's middle section, which indicated it had just consumed something -- so maybe that's why it didn't LEAP OUT AT US! And yes, I yelled at my dopey husband.
