Another option is to install StreetComplete on your phone and do something useful for society while on a walk
Ngl I like this idea. I highly doubt there’s much around me worth noting, but I’ll absolutely check it out and do what I can.
The things around me have all been stuff like “what material is the power pole made out of?” “What is the road surface on ____ street?” “What are the restrictions on parking here?” Etc. but there is an advanced mode you can use which unlocks harder questions that less people answer
