Took a road trip today to the Fort Wayne area to meet up on an animal transport to transfer an animal to another driver and our meeting location was a truck stop that was easy to get to and leave for both of us. While waiting for the other driver someone parked next to us at the very front of the car parking area where the parking lot light post is mounted on a concrete pillar. Woman got out of the car walked up to the light post and lifted the aluminum square cap over the light post mounting bolts and grabbed a medium sized prescription bottle and returned to her car. About 30 seconds later she took the bottle back and placed it under the aluminum cover and left. My guess was drug drop and buy. Anyone else have a reason that makes sense?
