The GPS tracker I placed beside the BH’s GPS tracker in an unknown third party’s car is still working. After visiting that tunnel beneath the freeway where we later saw the two Immortals, I don’t have the guts to check out in detail any of the places where it goes. But I don’t mind driving down an interstate (or its frontage road) and snapping photos.
This one is of a place he parked in.
