No real doubt - anything British Isles is fair game. So if I get to Listowel or Ballybunion I can tell you about it.
I voted for "British isles" but would add the caveat that posts about more distant attractions could be included if exceptionally important/interesting.
Repeated several times ... so I'm inclined to think that
the Cass Scenic Railroad can be included but probably not the
Seminole Gulf Railway. Cass, of course, is particularly inclined!
