I could offer lots of corrections. I think we have discussed this here before. Given the age of the Internet CAMRA is somewhat in the dark ages with dissemination of news. Although we do at least have postcodes for each pub now.
Here are a few important corrections:
Page 263: Grantham - Chequers. Pub closed.
Page 526: Langdale End - Moorcock Inn. Opens 1200 and does not open at all Friday lunch. This is correct for summer and not just winter. These times are not new and I cannot understand how they are incorrect in GBG.
Page 273: This really corrects NI booklet/website. Birmingham - Bellefield is closed and looking sorry for itself. Smethwick - Waterloo Hotel only sells fizzy stuff and some of the classic rooms are locked and difficult (impossible?) to inspect. Bloxwich - Romping Cat is for sale, but is still open.
