The great phone search

Usually when I can't find my phone around the house, I use another phone to text a special code to my phone that takes it out of silence mode and makes it start ringing, which makes it easy to find.  But this time, right when we were about to go for a hike with my parents and sister, it didn't work.  So we had to look for my phone for a good 15 minutes before leaving the house.  Eventually, I thought to use a browser to instruct my phone to take a picture to see if I could identify the scene.  I did so right as my sister was finding the phone.  (or maybe she was hiding it?)
