Went to Catholic school in Rochester and a big recess favorite was "King of the Hill" where one kid, or a group of kids, would shove people down the snow pile as they approached the top...being Western NY, this was a common November to March phenonium.
Also big was outdoor basketball, touch football and the occasional fight, which was most often quickly broken up by the gym teacher/recess monitor.
Springtime brought out the occasional water guns, but these hydro-powered weapons were very much frowned upon by the nuns in charge, if you were caught with one, it was a 25 cent fine...the same monetary penalty also applied to gum chewing, yo-yos, and playing with "clackers," the annoying balls on a string that when struck, emitted a clacking sound, hence the name.
