Perfect, pity that's not still going !.. One of the old 'uns used to go over the border to Enniskillen quite often and I always said "shame you don't know anyone over there".!
.. as a matter of interest a couple of our lot went over on the car ferry, from holyhead, a couple of weeks ago and (unlike the air route) there was no checks of any kind, passports, baggage, nothing..
Just sayin'.. 😉
