I'm going with some friends to the 22nd Bent & Bongs Beer Bash tomorrow, and I'll also be meeting my friends Ken and Carol of Wigan CAMRA there. This is a friendly little festival in Formby Hall in Atherton, around 10 minutes' walk from Atherton Station. Nearby there are a couple of good pubs you can retreat to after the festival closes, and we were so taken with them last year we nearly missed our last train back to Southport.
It's run by the Bent and Bongs Charitable Trust, in association with CAMRA, and it supports a number of local good causes, which are listed on their website, as are opening times and admission charges. It's just a 50-minute train ride from Southport.
