The question itself is an example, but it isn't the best example

Have you ever visited D.C.?

or

Have you ever visited D.C?

Both look wrong to me. The former has double punctuation, which is against the rules, at least most of the time. The latter doesn't have a period indicating that the C is an abbreviation.

I think this is General Reference/common knowledge. Obviously, many results returned by searching Google Books for Do you live in L.A. sidestep the issue by not bothering with either period. But I don't think there would be a single (valid) instance where only the second period was discarded (supposedly, "replaced" by the question mark). –  FumbleFingers Jan 27 at 15:52
