Not really. The whole parade, dyeing rivers green, stringing the celebration out for two or three weeks beforehand thing is almost uniquely Irish-
American. As far as I know they don't even do that in Dublin.
I know quite a few Irish people living here, and the most they do to celebrate is to go to the pub (and Irish pub if possible) and drink Guinness. As such I may celebrate it to the same extent as they do, especially as this year it falls on a Saturday. However, with our drink-centred culture, this isn't significantly different to a "normal" night out.
Indeed, I remember reading somewhere that much of the push to turn Paddy's Day from a simple national saint's day into a "celebration of Irishness" came about as a marketing campaign to sell more Guinness.
Besides all that, I'm Welsh anyway, so I'm more likely to celebrate St David's Day (1st March). This isn't the special occasion that 17th March has been turned into (perhaps because the Brain's or Felinfoel brewery haven't been as clever), but I do spend more time contemplating my Welshness (100%, none of this American-style "one-quarter on my great-grandmother's side which gives me reason to self identify as something I'm clearly not" stuff

) then.
It was a lasting disappointment to me that when I last visited the USA, I was in Boston on 1 March, and the green Paddy's day decorations were already all over the place, and there was not a single indication that anybody even knew it was the Welsh saint's day, much less that it was celebrated in any way.
OK, the ethnic history of the Welsh in the USA is different from the Irish; there was no mass emigration from Wales. (The USA's loss

)
And the Dublin guy working in the bar I talked to about it was as taken aback by the scale of St Padraig's Day celebrations in the USA as I was.
We speculated that, in the New England climate at least, it was as much a usefully-scheduled celebration that Winter is coming to an end (though it wasn't that year, being the coldest weather I have ever experienced, including on skiing holidays in the French Alps) as anything about Ireland. Including the ubiquity of the colour green - the colour of spring. This seemed plausible to me.
