The Bothy from the East.
The car is our Hertz rent-a-Chevy.  Irish license plate numbers follow a logical code: the first two digits are the year of first registration; the letter or letters following that are a code for the county of registration.  In this case, "LH" is the code for County Louth.
A measure of Ireland's decade-plus of new affluence is that we saw virtually no license plates with the first two digits being earlier than "98".
