Autumn term starts 30 August; it’s all the offices, etc., what have closed (and I think there may still be a summer session in session.)
Overly cautious? I had to snicker – Longwood has been known to close if there’s even a hint there may be snow. I lived in Minnepolis for a winter, and was very impressed with not only the amount of snow, but the general reaction to it, and I giggle every time people here freak out over a light dusting of snow.
Or it could just be that it’s a case of colossal cheek. Either way, for me, on hearing this news, was in serious danger of permanent eyeball damage.
School in Virginia does start in mid to late August, which I find very weird, too. I went to high school and uni in Delaware, where it starts after Labor Day. I have never got used to school starting in August. That’s why I’m moving back to Delaware next week 
An aside – when I was at the University of Minnesota for that year, the autumn term started at the end of September.
Anyway – crikey yes, Longwood, and the local county schools here seriously overreact to rain, snow, you name it. I think it goes back to a massive ice storm a few years back what caught everyone off guard with its severity, and ever since, they err on the far, far side of caution.
Look, there’s a tidal wave in Japan, a meteor hits the moon, a star goes supernovae 35 light years away – Longwood closes just to be on the safe side.
Ps on preview – I’m reading this out loud to my partner, and he’s laughing and agreeing.
