Here's our tentative schedule, as we're a tandem team:
Feb: Palm Springs? Or local self-supported
March: Solvang
April: Chico wildflower
May: Monticello (right out our back door!)
June: ?
July: ?
August: Marin (best food EVer)
Sept: ?
Oct: Foxy's Fall
Nov: ?
Dec: ?
Frankly, there isn't a bad century up here, as far as I'm concerned. In fact, you could probably do two or three a month if you wanted to.
Let us know which ones you ride; we can save a spot on our wheel for you.
