The ‘Pooh sticks bridge’ from the Winnie-the-Pooh stories is a real location near Hartfield, East Sussex. The Hundred Acre Wood is better known as Ashdown Forest.
There’s also the real Watership Down, near Newbury and the border of Berkshire and Hampshire.
Yeah, it was a Land Rover, come to think. Sorry about the misplaced product placement. 
And they did have a guide for the whole route.
And I wouldn’t quibble too much about lack of geographical knowledge, when 20% of Americans can’t even find the U.S.A. on a map…I’ve been a geography fan since childhood, and I’ve seen Jeopardy! contestants stumped by questions that I thought were common knowledge!
Actually Chefguy, almost all the posters so far, knew about those locations. It just happens that there was a period in the past when they were ignorant, but we got better…
A recent episode of South Park centered on Cartman and his desire to go to a restaurant called “Casa Bonita”. I figured it was something they made up for the episode until I googled it. Holy Crap!! There is a restaurant with cliff divers and caves! I wanna go!!
Oh, and I also didn’t know Sherwood Forest was a real place until I was about 10. D’oh.
In the film My Dinner with Andre, Andre talks quite a bit about his very bizarre experiences in a mystical community in Scotland called Findhorn. I had no idea that it is a real community until I found a recording that had been made there and later saw a book about it. Certainly a most unusual place.
Yeah, me too. Didn’t mean to sound arrogant.
Springfield (Illinois) and South Park.
Yes, obviously I know there’s a Timbuktu now, and where it is, and something of its history, otherwise I wouldn’t have mentioned it. But my mother used to say that high winds “blew [whatever] to Timbuktu” or that we had to go “all the way to Timbuktu” to find something. So imagine my shock to learn about the riches of Timbuktu and the African empires.
Although I can’t say I’ve quite been.
There really is a town named Bugtussell
There isn’t a Castle Rock in Maine, but there is one in Arizona.
And just in case you wanted to know:
There’s a subdivison in Annapolis Maryland named “The Village”
There’s a road not to far from where I live named “Green Acres Road”
There used to be an estate in Annapolis named “Bag End”
Springfield is the Capital of Illinois.
No, Dangerous Nan, ya don’t. Trust me. Casa Bonita’s food isn’t worth eating. And the “entertainment” isn’t worth watching. But there are lots of sopapillas…
Ick, man. Don’t do it.
Snicks
Sort of. If you’re talking about the place in Tennessee, I think the actual name is Bug Scuffle.
Then there are the instances of “life imitating art” in a way that Oscar Wilde would approve of.
In 1988, the Beach Boys wanted to record a “tropical paradise” song and needed a three syllable name for the place. They sited it on the Florida Keys, which did not have a suitable place name, and borrowed the name of the county seat of Howard County, Indiana (pop. ~50,000), perhaps because it was originally the name of the chief of the Miami Indians.
One of the Upper Keys – I’m not sure whether it was Islamorada or Upper Matecombe – picked up on it and adopted the name “Kokomo” from the song as an alternate name for the community, with resort motels and restaurants naming themselves after the song.
So, while “In the Florida Keys, there’s a place called Kokomo,” was fictional when the song was written, it now does actually exist.
In that vein, the radio station WPLJ in New York city was named after a Frank Zappa song. The station changed its call letters to WPLJ a couple of years after the song came out.
They may have also been influenced by Chuck Berry: “…no particular place to go, so we parked way out on the Kokomo…”, from the song “No Particular Place To Go”.
I just remembered something from the classic The 3 Musketeers:
I knew it was historical fiction, I was still amazed to find so many of the characters were based on real persons:

That is from a fencing site, but it matches other historical sites I have seen.
Similarly, an Ohio radio station called 97X, which used a number of slogans over the years, has constantly used the slogan “The Future of Rock 'N Roll” ever since it appeared with their call letters in the film Rain Man.
In “American Psycho” there’s all kinds of talk about a restaurant in NYC called Dorcea. ex: " I got an 8pm res. at Dorcia"
There’s is a club in NYC called Dorcia but I am told that it opened after the movie. Maybe some NYC dopers can confirm?
