Considering Wales is part of the English cricket association it would be wrong not to include it. I missed it as well because I was too busy typing cardiffshire
It should be included but the title of the quiz changed. Glamorgan isn't a member of the 'English cricket association' because there's no such thing. It's a member of the England and Wales Cricket Board - which rather proves the point.
Title and intro text should really say First Class Counties. There are Minor Counties too, after all. https://en.wikipedia.org/wiki/County_cricket#Minor_counties
good quiz
