Mrs. Lee drove my car to the airport, long term parking, while I was on a business trip, as I was coming home the next day and she was flying out the previous night. I told her to take a very clear photo of the parking row and space number, so I could find my car when I arrived. This is what she texted me after she had already gotten onto the plane.
Now, this row is only about 2000' long and I was arriving long after dark. What could go wrong? I knew from the time stamp and position of the sun which direction she was facing when she took it. That got me within range so I could see the lights flash when I hit the key fob. Had I done this to her, I'd have to get the car myself after paying for a week of parking.
