The socialists don’t like families bonding during summer break which is why they want to indoctrinate the kiddies year round!
I think they also start earlier to build in more snow, ice weather days. Seems like even the treat of a snowstorm and school is cancelled or delayed.
I think in my whole 13 years of schooling living in Iowa at the time we maybe had 10 days off. Most years none. I think one year there were 3 snow days. We thought that was amazing.
