It is a game which involves a group of
people, preferably the more agile, to go to a
children's 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
one's eyes closed on complex surfaces!
Grounders is a game that I only know of existing in Vancouver, British Columbia but may exist elsewhere.
