After a brief inquiry to my neighbor who has a doorbell camera about the mystery of the big black van, we learn that the driver was just a hapless hooded delivery man who made perhaps not the wisest choice of parking on the wrong side of the road , no doubt to speed up his duties. I am flooded with relief that at least in this instance I’m wrong about the situation and there was no immediate danger present. Thank goodness for technological helpers and the friendly neighborhood watch.
