Do you know what I mean? Where you get a state, county or region which forms a 'block' of continuous land, but there's a separate small part of it 'next door', or nearby, surrounded by the state, county, country next door. So this little fragment is in no way physically joined to the rest of the state/county/country.
I believe the Spanish state of Valencia has one, and I think I've read of English counties with that oddity!
Anyone know, or can give me some examples?
