Chowder:
hot showers that go on forever…We have these y’know…not where I’ve stayed!
front porches with swings…but very few of these
iced tea…Yup, got this. True enough.
lots of ice in my drinks…and this. 3 cubes is not “lots”
economy sized grocery products…these as well. Never found because never needed?
road signage I can understand…and these. 2 countries separated by a common language…
not having to pay to pee in a public place… :dubious: Several train stations in London require cash–a turnstile type thingy, with an attendant (or janitor)
cab drivers that just take you where you want to go instead of berating you about your country of origin’s foreign policy and wealth etc. ::cough, cough:: Cabbie in Dover–abused me (I was alone) and my country for the whole trip. I waited until he had unloaded my stuff to tell him he wasn’t getting a tip.
laundry detergent in English/Spanish instead of Chinese or similar…got this. Where? The only detergent I saw in London was English/some type of Asian writing.
flat or minimally rolling hills with wide open blue sky all day long…got the hills, not the sky. I miss the Midwest sky when I’m in NEW England…
violent thunder storms/hail storms/blizzards…Oooh, we get some stonking storms. My friend in Yorkshire says you don’t. 
barbeque…only in summer. Real BBQ, silly!
biscuits as a bread product at a meal…nope. But scones are heaven.
cookies–real American cookies, drenched with chocolate chips, nuts and loaded with refined white flour, sugar and nothing good for you…got 'em. Not easy to find. Digestive biscuit sounds like a homeopathic remedy, IMO.
Dairy Queen ice cream cones…nope Frozen yogurt would come close.
yes, even baseball news–at least news about the Cubs…nope (Thank Og)
Really bad small business TV ads: “I’m Homer Fudd and I sell cars!” sort of thing…we have crappy ads. But even your crappy ads I find fascinating.
newspapers with American focus…some American coverage is unavoidable. True.
Thought of another one: lemon wedges in table water. Heck, water provided at restaurants w/o asking. With ICE. 
Oh, and one more–a smile when checking in to your B&B would be nice. I don’t need to become your new best friend, but a small courtesy would go far. (this applies only to a certain landlady in Durham who was the most repressed person I’ve ever met. She made Lot’s wife post-glance back look animated!)
