A necessity: The annual Good Beer Guide, because it lists 5,000 pubs recommended by local Camra members.
A luxury: The one thing I have in my car is a Bee Gees tape, which my wife and son love singing along to.
A memento: I collect Toby Jugs, and whenever I'm out looking at pubs I visit antique shops and car-boot sales in search of them.
If only: Landlords kept pubs open when they say they will. Also, pubs should be child-friendly.
