Landsdowne is practically falling tp peices. Compring Landsdowne to other, for example, 6 Nations Stadiums, it's the worst of the lot, and a bit of an embarrassment, especially when we have Croke Park lying idle. Bring it on is what i say!
Unlike yourself and it seems most of the Irish public, politicians, commentators, etc. I have no real problem with the current state of Lansdowne. Sure, it's not modern or cool, and if you're the type who'd be too embarrassed to be seen driving a 12 year old cheap Ford, for example, then I suppose it might discomfort you worrying what the neighbours think. The entire east stand and terracing are absolutely fine - great views from everywhere in the east stand and great cauldren like atmosphere on the east terrace. There are a (very small) number of blind spots in the west stand but 99.9% of the seats have great views. The north and south terraces are o.k. too as far as terracing goes.
Like I said before, I'd rather be able to get a ticket for the big rugby internationals and watch the game in an old-fashioned stadium, than watch the game on telly knowing that the well-connected (via the blazer or corporate channels) are able to watch the match in more comfort. So for me (a person who has been attending matches in Lansdown since I was a child), the only real problem with it is capacity. Besides safety, everything else is secondary and I've been to some of the superb modern stadia like the Millenium in Cardiff.
Don't get me wrong, I actually really like the proposed design but the reality is that without an increase in capacity, for me, this is essentially a very expensive vanity project.
