I want to know the answer to the following question:
On what days were Scottish and Welsh pubs often 'dry'?
All the background I'm provided with is that "During the 20th century elsewhere, both the licensing laws and enforcement were progressively relaxed, and there were differences between parishes; in the 1960s, at closing time in Kensington at 10:30 pm, drinkers would rush over the parish boundary to be in good time for "Last Orders" in Knightsbridge before 11 pm, a practice observed in many pubs adjoining licensing area boundaries.". Is that enough to answer the question?
Answer: no
