Sunday 25th May is of course the Towel Day. So don't forget to bring your towel with you all the day. If you want to get more informations about towel day, here is the official website :

The day before, Saturday 24th May, ZZ9 PLural Z Alpha, the officiel H2G2 fan club, organizes a guided visit in Cambridge : "Cambridge Slouch 13:00 meet at Cambridge Railway Station and we will decide what to do, as it depends on the weather. Recent Cambridge slouches have visited various Douglas Adams related locations in the city (his birthplace, his college, places where he performed in plays and revues), the Botanic Gardens to see the flowering of the Amorphophallus titanum, the Fitzwilliam Museum to see an Egyptian Book of the Dead, gone punting, and had the odd pint in various public houses.'

ZZ9 it's here!
