Varsity High school sports, back in late 60's Toledo, OH:
fall: football, wrestling, cross country, golf, tennis, begin basketball
winter: basketball, wrestling, swimming
spring: end basketball, baseball, track, golf, tennis
fall/spring: city soccer league,.. HS club level
summer: I believe there were some rules not to play organized varsity sports.. till football tryouts in late summer
summer: AAU sports: baseball, track and swimming
You played sports of the season and held on to passing season until major league championships were done.. not unusual in summer to play baseball or golf in AM, go swimming and play tennis in afternoon..
Sledding and tobagganing were prohibited in winter if you were on a varsity sport.. no one ever enforced that one..
Columbus more ice than snow..
