Think they've tweaked the humidor settings just a bit at Coors lately? The Washington series had totals of 15, 19, 14, and 22? And last night against San Fran, 28??
If they don't turn the humidor setting back to "high", one of the games in the upcoming Atlanta series will wind up being like 37-28 or something (with Atlanta probably winning). Really, if they don't turn it back up, all of the Atlanta games and all of the Dodgers games after that will be good over bets. The books probably won't suddenly tack on an extra 3 runs to Colorado home totals, but who knows.
We'll definitely be doing humidor research at the beginning of next season.
