Well all i'm saying is if I saw a MJ plant, i'd stop and look, plus the route he took may have been because your neighbors meter is on the back of the house, these people have a route and they aren't there to spy, just record numbers. If I were him I'd be thinking a dog is gonna attack me, or the homeowner is gonna yell at me, they just get in and out. checking 70+ meters in a neighborhood is tedious, but you can only spend like 5-10 seconds at each so walking to and from has to be done fast. Just put yourself in his shoes, go walk through a bunch of strange yards trying to find meters and then do another 4 hours checking in other neighborhoods and think if you can remember any of them.
