Just typed out long explanation but lost it so try to shorten. Last February and today I was approached by a man apparently asking for directions but then changing to ask about local eating places. The reason it may be suspicious is that although polite and not physically threatening at all, both men changed from initial inquiry to explain they were from another particular city so had apparently randomly set out alone in a car to travel over 20 miles to find something to eat in place they don't know. The first man never got out of his car parked across a driveway, the second was on foot at first but had a car parked across the road. They had similar characteristics but I cannot be sure if the same man with the same story or different men. What if anything do MNs think?
