I wonder if todays kids ever do that
Play marbles, I doubt it. Sure haven't seen any games going on or even sacks of marbles for sale. Used to be a big thing, citys would hold tournaments and the winner would go to the national tournament.
We sure used to have a lot of marble games going on especially after school. Grandma would always warn me "now don't play for keeps", but I always did anyway. Seemed like all the boys and quite a few girls in grade school were fans of marbles. I suppose gone via computer games.
