You usually see these on fields that are co-owned or need to be accessed by several municipalities. Everybody gets their own key but can still have access to the area whenever needed.

I didn't think about how sad it will be to lose askhistorians 😞

I hate to say it but shitposts and circlejerks are a bit part of my reddit browsing to lighten the mood.

Otherwise, trash like terriblefacebookmemes and idiotsincars was great entertainment for some reason...

I don't know why I am like this.

Edit: to extend on this, seeing a post about some crazy shit play out and then reading everyone react to it is so much fun.
