Grounders

Grounders is a game that to my knowledge exists in Vancouver, Alberta, Calgary, British Columbia, and Newfoundland, in which a group of people will climb around on playground equipment and try to avoid being tagged by the blindfolded person whom was designated as "it". the rules of the game are as follows: One person will be chosen to be "it" If they have never played the game before or they showed up late or something they are automatically chosen to be "it". Sometimes the person that is chosen will be instructed to close their eyes and spin in place for 10 seconds so that they can be disorientated while also giving the players a chance to move around a little bit. during the game if "it" hears someone trying to sneak around on the ground they can yell "GROUNDERS" and the round ends and the person that got caught is now "it". Its true origin alludes me.
