To me, joining CAMRA is akin to joining the National Trust, i.e. you only really benefit from it if you live in mainland UK.
Unless you're a fan of the delightful Wetherspoon's....

P.s. I've been a National Trust member since 2009 and have already seen all I'm going to see of Florencecourt, Mount Stewart, etc. I'm saving Patterson's Spade Mill in my bottom drawer for a special occasion.
