Being a guy who likes maps, I have been using OpenStreetMap a fair amount recently. Basically it’s Wikipedia meets Google Maps, an editable map that anyone can use and anyone can change. Don’t see your house on there? Add it! Your favorite bar is missing? Put it on there.
It’s pretty fun, and a great resource too — unlike Google Maps, everything on there is licensed under Creative Commons, meaning anybody is free to use the data as long as they attribute it. It’s a fun resource for just browsing around too.
So check it out, and see if you can add anything! Maybe you’ve been to some other town and can add some things there too?
