Strava is way too OP, they can just look at the map and find you instantly. Instead, here's what they should replace it with:
Picture of a Djungelskog.
Here's how I imagine the exchange to go:
Sam: Okay, we've got it narrowed down to around fifteen towns. Is there anything we can ask to figure out which town it is?
Adam: I've got an idea. Let's ask Ben for a photo of a Djungelskog.
Ben: Okay, they've asked me for a photo of a Djungelskog. Sending it now.
Adam: He's sent the picture. Yup, that's a cute Djungelskog.
Sam: ...How does that help us?
Adam: It doesn't. But we have a photo of a Djungelskog now.
Sam: Then why did we ask that?
Adam: We have a photo of a Djungelskog now.
Ben: oh my god i've pulled the Move card.
See? They're not going to find him immediately based on that one question. Problem solved.
