On this day, fans around the universe proudly carry a towel in his honour.
Simply turn up with a towel and stick your thumb out to try and get a lift from a passing space ship.
The event will start at 7pm and finish at 7.30pm (officially) in the venue we usually meet, 'neath the old Viaduct, just south of Cork city.
Being a fan of the Hitchiker's Guide To The Galaxy stories is of course not essential - this is a Geocaching event and if you just turn up for a chat, that's great! If this is your first event - all the better!
I will of course ask if the venue can serve Pan Galactic Gargle Blasters just for the evening... but can't guarantee that they'll come close to the correct recipe that'll have the effect of "having your brains smashed in by a slice of lemon wrapped round a large gold brick"...
