As noted, that was a previous year's ride. Rob (our RBA) has just submitted the 2014 calendar. If you are interested, you should join the SFR which will put you on the email list for announcements. Joining is free.
And, I'm NOT going to try to tell someone from MN what weather is like, but January is "winter" in the SF Bay Area, and if you poke around in the archives (JimG via
yojimg.net has some ride reports) you'll find that some years it is unutterably beautiful, but some years - the wet years - can be some of the soggiest, dampest, coldest times you might spend on a bike.
But, yeah... it's a great ride -
