Well, look at the bright side, long-range weather forecasting (as in, more than a few hours!) is a pretty hit-or-miss proposition out here. I'd say they have a 50% chance of getting it right. So the chance of rain is actually somewhere between 90% and -10%
Oh, and AG, I think you're absolutely right about the seat position. Much better to tinker with the stem height and extension rather than the seat position, for the reasons you said.
Then again, I'm reluctant to mess with anything before a big ride; I just got a call from Rivendell telling me that my long-awaited narrow width Nitto Noodle bars have arrived, but I probably won't swap them out until Sunday.
