When I was still in college (Oxford, UK), students and city residents contributed this open source google map called 'Food for Free in Oxford' where you could drop location pins to indicate foraging or hunting spots. Of course, we had to label the pins appropriately to indicate what sort of food you could forage/obtain. You can google the map online, it's really comprehensive -- you have hundreds upon hundreds of pins marking locations with berry bushes, fruit trees, mushrooms, herbs and even crayfish. Students used to, and still do, walk to these spots using GPS (think Pokemon GO) to collect free food, especially during the spring and summer when plants start to bear fruit. I was wondering if we could start a similar initiative on this site.
