We used to play a game in the i950’s in charleston s.c. and we called it half rubber or half ball. we didn’t know anything about pensie pinkey’s or spaldeen’s we would take any kind of solid rubber ball and cut it in half. Man, what a fun game, it was played on the order of baseball but no running to the bases. Has any one out ther ever played this game? If interested I can give you all the rules.
