If I can get the time off, I'm also thinking of doing the double metric. The guys in our club always do that route as they too say the beauty is worth the climb!

SK- if you want to get a metric in this weekend, the Benicia club is starting from the Valley Cafe in Rockville on Saturday morning at 9:00AM. They are going to do the ride to Berryessa via M Corner the reverse of how we did it last year- with an option to do Cantilew on the way back. I think the total distance is something like 60 miles. I'll email you if you want details. Should be a good ride for some not too hard climbs and some good distance.
