Well, there is always plenty of stuff available in Wales to celebrate it, but then Welsh cakes, although nice, aren't as exciting as Guiness, for most people. I think although it's definitely commercial - no-one really minds an excuse to drink and eat, just like at Christmas and Easter.
Right. My ambition now is to plan the mass-marketing off the back of St. David's Day. St. George's Day needs no help, in Clinton's at least, and I suspect is fuelled quite nicely by the football industry.
Guinness USA certainly capitalises on St Patrick's Day over here -- they've shown quite a few ads on TV here equating St Patrick's to Christmas, with everyone getting cases and kegs of Guinness and Harp....
[Nik] If St George had been asked what his birthday was, would he reply, "Nik's birthday"? (NB Nik's email address removed by request -- rab)
[ZK] I'd help you with the American marketing of St David's Day, but most Americans wouldn't know a Welshman if he came up and shoved a leek up their collective arses. ;) See also Church, Charlotte, meeting George W. Bush
[HB] Nowt Welsh at all, I'm sorry to say. Although I have tried and dislike laver bread, I would have bought any (or all) of the other items that you mentioned. I would also like to mention that difficulty my Irish father-in-law suffers in trying to find me a St David's Day card, on the back of my always sending him a St Patrick's Day card. Sceptics, note - he managed it once, so such cards do exist!
