I have racked my brain all day and I still can't think of an island

[Atticus]

that is not "surrounded by water".

[Sneederbunk]

1. But we are talking "big water."

[Ms. Toad]

2. Here's one:

Grand Island, NE

[HipChick]

3. Even the US is an Island...

eventually....Turtle Island..

[leftofcool]

11. And stolen

[world wide wally]

4. Grand Island, Nebraska?

i just noticed Ms Toad already got that one
So, how about Rock Island, Illinois?

[dweller]

5. Isle of Langerhans

😁 I can't remember the riddle I learned this from ...

[unblock]

16. Usually called islets, but still a good answer ;)

[grantcart]

21. beat me too it

[csziggy]

32. I learned it from Firesign Theatre!

About 3 minutes in:

[lostnfound]

6. General Mattis

An island of character and sanity surrounded by a sea of idiots and con men.

[Turbineguy]

7. Then you are obviously waaaay too

smart to run for president in the republican party.

[ProudLib72]

8. Avery Island, LA

Where Tabasco is made. It's inland but surrounded by marshes. Does it count?

[Binkie The Clown]

9. Islands on Jupiter might be surrounded by liquid methane or ammonia. nt

[Blues Heron]

10. rhode island?

I think it might be surrounded by a bog though, not sure

[Leith]

12. Isle of Lucy

Say it out loud.

[SergeStorms]

24. Spinal Tap!

The "Isle of Lucy" was one of their favorite places to play.

[Leith]

31. Well, I Got It from the Rocky and Bullwinkle Show

One of their "side" cartoons talked about the Isle of Lucy in the middle of Veronica Lake.

[SergeStorms]

33. Well...

Rocky and Bullwinkle came before "Spinal Tap", so that's where Chris Guest et al. gleaned it from I guess. You learn something every day. Thanks for that!

[WinkyDink]

26. :-)

[underpants]

30. You got some 'splaining to do dis time

I'd forgotten about that

[Takket]

13. We should send drumpf and family to Rikers island

Then maybe he will understand what an island is

[nocalflea]

28. Alcatraz.

Give 'em each a blanket and a bucket and let the tourists throw peanuts at them.

[arthritisR_US]

14. Your moron and thief had to learn what an island is.

[matt819]

15. Australia

If he considers Australia his head will explode. Island. Country. Continent. Ocean.

[Maynar]

23. Perhaps that could be a catalyst.

[Cracklin Charlie]

17. But the difference, Atticus...

Is that when you woke up this morning, you already knew that Puerto Rico was an island.

You didn't need someone to explain that to you as if you were a five year old.

[Hassin Bin Sober]

18. You've obviously never been to Blue Island Illinois

My dad's old joke:

I'm taking the family on vacation to the islands. Blue Island, Stony Island and Rock Island.

[0rganism]

19. has Orange Ocean Man thoroughly confused us all?

has Ocean Man taken us to a land that only he understands?

[world wide wally]

20. No man is an

"I" land

[edbermac]

22. I somehow flashed to a scene in Jaws.

Brody: It doesn't make any sense when you pay a guy like you to watch sharks.
Hooper: Well, uh, it doesn't make much sense for a guy who hates the water to live on an island either.
Brody: It's only an island if you look at it from the water.
Hooper: That makes a lot of sense.

[DFW]

25. There's always Rhode Island..... n/t

[WinkyDink]

27. People are misunderstanding the OP! Puerto Rico isn't called "Puerto Rico Island." The OP asks what

small "i" island---i.e., an island IN REALITY---is not "surrounded by water."

Clearly, there are places NAMED capital-"I" "Island" that do not merit the designation!

IOW and IMO, the OP was rhetorical!

[democratisphere]

29. Islands that are not surrounded by water are everywhere.

Everywhere.
