We're the same. I grew up in MA and currently live in NY and school always gets out in late June (usually 3rd week) and starts the day after labor day. I'm always shocked when I hear how some kids go back in early August! Even mid-Aug still seems so early to me...it's still summer! To me school start = fall. School end = summer (June 21st or so being the usual first official day of summer.) Not a perfect match up since summer doesn't officially end until late Sept, but it's close, since it usually starts getting cooler here in mid-Sept. Is it the weather that causes the different shifts in school times across the country?
I'm watching this thread closely now since we still haven't chosen when to make our Disney visit in 2018.
