somebody find that stats of how many times it rained during a game since 2003 . i will put anything on it that its less then 5
You'd lose. What confuses some is the unusual fact that it didn't rain on a game in the first three years (IIRC) of the new stadium. It was quite weird, as the odds of it not raining on any given Sunday afternoon between Labor Day and New Years has to be astronomical. After '04-'05 or so normality returned and we started getting rain several games a year.
As a season ticket holder from 2005-008 or so, I can attest that we got quite a few games where we had rain/weather.
Not sure what the long term forecast is for Sunday yet, but nobody around here trusts any forecast more than 3-5 days out anyway. By Thursday or so, we'll have a better idea of the projected weather.
Incidentally, rain has pretty much zero effect on footing. Sure, the ball gets wet, and we do have some interesting wind affects sometimes, but it's often not that big of a deal.
I think another reason the myth still exists is that rain is hard to notice on television if it's not pooling up, and our field drains so well, you just don't get big pools of standing water when it's raining, so unless you look really closely, you might not notice the rainy days on tv
