There's a famous motorcycle road race in Northern Ireland called the North West 200. Many years ago I rode my bike from Southampton to Fishguard, caught the ferry to Eire, stayed over then rode to Limerick then Dublin then to Enniskillen then to Belfast to meet Mrs N (who flew over in her bike gear). We watched the racing for the weekend then I dropped her back at Belfast airport and took the ferry to Stranraer (then did Stranraer to Southampton in one hit, ouch).
The ferry is a aircraft hanger sized fast cat, must have held a good 5 or 6 hundred bikes, as we rolled off the ferry and through the town of Stranraer the good people were lining the streets and waving flags and all sorts, was a good start to a 12 hour ride!
(The flags were Union Jacks and so forth btw not "Bikers Go Home"
