Grounders

[Mark Zuckerberg]

It is a game which involves a group of people, preferably the more agile, to go to a childrens playground (the more complex the better) and to have a contest as to see who is it and the others are to hide around upon the playground works while the person who is it tries to find these others while the it person has closed eyes or is blind-folded. The others can move to other areas of the playground but must take great care when moving or especially on the ground. If the person who is it calls out GROUNDERS while someone is traversing the ground to another area that person becomes it. Another way to pass the it status is to tag someone.
The game usually becomes more fun if the participants are intoxicated on alcohol or marijuana or other things. It is also fun if a member is overweight or typically scared of jumping around or having ones eyes closed on complex surfaces!
Grounders is a game that I only know of existing in Vancouver, British Columbia but may exist elsewhere.

Grounders is a playground tag game also known to exist in Calgary, Alberta.
Minor injuries are quite common as a result of navigating the complex surfaces blind. These injuries may result in great humour to the other participants. Often, if one or more people have not yet been it or have tried to cheat, the others will gang up on them to put them in a position where they will more likely get caught.
Variations of Grounders include allowing the person whos it to have their eyes open while on the ground but closed on the playground area. While on the ground, they can then reach in to try to tag people.
