I'm sure many will think this is heresy, but I really, really, REALLY think teams that have put up new stadiums in the last 20 or so years should have taken a cue from Skydome rather than Camden Yards.
We're already had one Opening Day rainout & 2 others are being delayed. Now I love the old school charm of Camden Yards, but these days "dome" doesn't have to = "monstrosity". Safeco is proof that you can combine common sense with aesthetics. And while it's true that there's nothing better than a ball game played when it's in the mid 70s under a clear blue sky, it's also true than in most places those other 78 home games can be a real problem.
From a team's point of view there's nothing that screws up a pitching staff more than about a gajillion unscheduled double headers in Aug/Sept. And from a fan's point of view there's nothing more annoying than settling down for a game & getting Rain Delay Theatre.
But instead of moving foreward most teams that are building new stadiums seem to be regressing. 2 non-domes going up in NY. And 1 in Minnesota, of all places. Yeah. Good luck with that.
Sorry, but with today's technology & engineering there's just no reason for it. Rainouts have about as much place in the world of 2008 as meat rationing, scrap metal drives & John McCain.
