“So, how on Earth would fellow American members describe the season. ie. 'It's really Wintery/Summery out there'.. 'It's very Autumnal today'... so what would replace 'Autumnal' ?”

That really made me think for a little. It’s common to use sports, due to the close association of baseball to spring/summer and football to fall/winter. You might hear something like “Perfect day for baseball.” for nice summer day or “Its starting to feel like football weather.” for a cool fall day. Of course that would be American football that’s played from September to December/January.

I haven’t seen the series you mention but I would imagine that, not unlike many travel shows, it highlights what is different more that what is the similar. You’re right though, we are a vast country and could be split into any number of countries. Of course that was tried out about 150 years ago and it turned out to be a bit of a mess. It also comes up in Texas from time to time.

I’ve always been fascinated with cultural differences and particularly the differences of American and British English. We speak the same language but it’s so different. Cars are a good example, wing/fender, windshield/windscreen, hood/bonnet, trunk/boot and (convertible) top/hood, to name a few. You could go on and on with little things. Some I get some I don’t. Torch vs. flashlight makes sense to me. A battery with no charge is flat vs. dead, not so much.

And lastly Chicago style deep dish pizza is way better than New York style thin crust ;)
