Nice catch! I'm with you, sometimes I wonder why I lug 45 pounds of gear with me everywhere I go (yes, I mean everywhere, even the grocery store). But it only takes that one time when you don't have it. That's when the UFO or Big Foot will show up.
Well, she really wasn't moving all that fast. I was about 50 feet away, and she didn't really seem too concerned about me. We first spotted her laying down chewing cud, so a half hour later I went and grabbed the camera. She finally stood up, lulled around munching on a couple branches, then decided the grass was greener in the neighbors yard. I took 169 frames over 10 minutes from 3 locations.
