Upon arrival I met someone with a phone hiding in the shadows near a fence. I just stood there, countering her actions and waiting to be noticed. A kid yelled, "mom! are you coming?", to whom she replied "yes, just wait one minute". After that she noticed me standing there, so she told her kid to go and bring his dad. Moments later I was surrounded by three Ingress players and had to accept those portals are to be theirs that night.
We talked for about half an hour, exchanging stories about the city and Ingress community in it, all in completely friendly atmosphere. I haven't met them IRL again since then, but they take my portals over every now and then :).
It was only a few times and it was back when I was to low level to take down claimed portals.
I'd plan a route to open portals in surrounding towns on the intel map (after farming as many resonators as I could).
Of course I'd be farming while playing the route so I'd always have more resos than I'd planned and the next town "wasn't that far" and "I've already come all this way", etc. etc.
Forgetting that the drive home was now hella far.
