In Texas, the state flag is displayed everywhere. It is common, at least in the Dallas area, to see the Lone Star flag displayed at apartment complexes, office buildings, and used car dealers. Is this common in other states? I don’t remember state flags in other states being displayed so often.
My Ohio experience has been to really only see the state flag at government buildings. I guess that’s because people don’t take pride in being Ohioans, in contrast to Texas if the stereotype is true.
(current state)
I’m not even sure what the Ohio flag looks like.
Previous states:
Tennessee - I saw it occasionally, mostly at government buildings.
Georgia - about the same as TN
Mississippi & Maine - rarely saw them that I can remember.
I used to live in Ohio. Columbus, the capital of Ohio. I never saw the Ohio flag except at state buildings. Here is the flag of Ohio. It is the only state with a pennant for a state flag.
Many fast food place, hotel and other medium to large businesses have three flags here in Hawaii. Their flag, the state’s flag and the US flag. Since it’s also the flag of the Kingdom of Hawaii you do see it very often. Although not as much as the Texan flag as I recall.
The Indiana flag is a thing of beauty, with a torch and 19 stars, but you don’t see it much. Outside of government buildings, fraternal organizations, and banquet halls it is seldom seen.
Our new governor Mitch Daniels held an online poll to pick the paint job for the big motor home he’ll travel the state in. The winning design looks just like the flag. I guess we all love the state flag, but we never fly it.
I have two US flags, which I occasionally fly. I prefer the Betsy Ross model to the 50-star one. I don’t own an Indiana flag.
I see the California state flag quite a bit.
I guess all the local lefties like the fact that it has a bear and a red star in it, or something. 
The South Carolina flag is quite lovely, but it seems like you don’t see it like you used to - flagpoles would have both flags (and maybe a company flag) more often. (Or the Stars and Bars - sorry about that.) What you do see a whole lot of is the flag in different colors, like garnet and black for USC or orange and white for Clemson. I think that’s a pretty interesting phenomenon that I haven’t seen in other states.
Probably because they have ugly-ass flags. 
Occasionaly you will find the North Carolinia flag being flown, but it is far less seen than the Stars and Bars. Schools and government buildings are about the only ones to fly it.
Back in CA, yeah, the flag is a pretty common sight.
When I lived in MI, hardly ever saw the state flag.
Here in IL, I see the state flag occasionally, but what’s really common here in Chicago is the city flag. In fact, at first I thought the city flag was the state flag because I’d never seen a city flag so omnipresent.
I live in Madison, WI - the capital of the state, for those not in the know - and I can’t recall that I’ve ever noticed the state flag in the two years we’ve been here.
Obviously, it’s flying somewhere on the capital grounds, and I’m up around Capital Square quite a bit, so I’ve likely physically seen it, but I’ll be damned if I could tell you what it looks like or where it was.
Back in Maryland, I saw the state flag moderately frequently, but then, it’s pretty distinctive and jumps right out at you.
When I lived in NJ, I only saw the flag around government buildings, court houses, etc.
In PA, I’m not sure I ever saw the flag. In fact, I"m going to have to do a search for it now, I’m not even sure I know what it looks like.
Here in CA, I see it all the time.
NJ: State buildings, and that’s pretty much it. Mostly because the flag, like many things in NJ*, is ugly as ass.
NM: I’d say I see it a moderate amount, but that could just because: I don’t get out much. They fly it on the flagpole on campus, and in front of the (state) office where I work. I think it’s a cool flag, FWIW.
*This is, keep in mind, the state where the most recent license plates are, apparently, designed to look like smog. Or posible smoke from a severe chemical fire. There’s no other explanation, really.
It is interesting to note that the state flags that seem to be seen the most are the ones that you can actually distinguish as being what they are, as opposed to the 20-25 state flags of the “state seal on a blue bedsheet” variety, which all look the same.
You didn’t ask about Canadian provinces and territories, but I’ll answer anyway. As I’m sure you can imagine, you see the fleurdelysé just everywhere in Quebec. This weekend I’m in Toronto, and I see the Ontario flag relatively often (i.e. not just in front of provincial government facilities) but nowhere near as often as in Quebec. I should point out that it’s not just a sovereignist thing, and companies and so forth, as well as individual federalists (such as myself), also display the Quebec flag a great deal, often in conjunction with the Maple Leaf.
I would guess that Newfoundland and Labrador would probably come next after Quebec, though I have no evidence for this.
HEY! :mad: We got the whole freakin’ PLANET on our flag, that’s how important we are! You gotta problem wi’ that?
Ever since 9/11 there’s been more US flags flying and decals stuck in store windows than usual around the city, of course, and every anniversary people drag out their flag scarves and jackets and even do-rags. But the state flag, NSM.
However, NY does have a lot of parks and the last Commissioner was crazy about the flagpoles. He replaced the old single ones with yardarms, on which you can fly the US and state (sometimes city) flag. Even the half-acre ‘vestpocket’ parks have them. State parks took up the trend so you see it there too. And of course we have tons of parades so people carry them, dipped a little next to the Stars and Stripes of course.
However, I too was truly amazed at the amount of Canadian flags I saw in Halifax and Cape Breton. Even my great-uncle used a string of them as decoration for his fishing boat like we’d use plain triangular colored ones, and the Busker Festival in Halifax had like three arranged on every lamppost. They were also used a lot in ads. It was amazing.
Damn, beat me to it. The city flag is all over the place here, including as a patch on Chicago cop uniforms.
The Kentucky flag is not often seen.
However, “UK” flags are everywhere. Lexington isn’t really much of a college town, but it’s definitely a college sports town.
