1) Nominate a date for the pub crawl (Saturday? Sunday? Friday night?)
...and while you're at it...
2) List your favourite pubs. Is the city easiest for everyone? Or would people prefer a change of scenery? Beach pubs, for example?
(Don't forget that you'll need to bring some knitting that requires no pattern and no shaping - depending on how much you intend to drink. I wouldn't recommend tension squares, as the chances are that your tension when well loose on the loosening juice is probably different to your regular (sober) tension.)
