Talking of pub crawls, Llani boy (probably better than I, we moved there in '86) will well recall the glory days of Llanidloes, I forget how many pubs now but people came from miles around for a night out, it was the ultimate pub crawl. It was renowned for the "multiple choices" and you could then end the evening in The Swamp! Happy days and fancy dress night was something else, close to anarchy before health and safety, rules and regs came in.
Edit: Best pub crawls would make quite a good conversation.
