Much like our forefathers who were limited by season and weather

Wildwood - Much like our forefathers who were limited by season and weather to plant, grow and harvest, most Americans who live in our region are limited to the temperate summer weather for comfortable vacations. At some point, Labor Day came into being and became an unofficial point to end those vacations. Why do schools now find it necessary to wrap up in May and begin in August in this region, when mid-June to Labor Day was okay for generations? This makes it hard for businesses to hire kids who they can rely on to stay the course until Labor Day. What is accomplished better August to May?
